about_psrule_assert SHORT DESCRIPTION Describes the assertion helper that can be used within PSRule rule definitions. LONG DESCRIPTION PSRule includes an assertion helper exposed as a built-in variable `$Assert`. The `$Assert` object provides a consistent set of methods to evaluate objects. Each `$Assert` method returns an `AssertResult` object that contains the result of the assertion. The following built-in assertion methods are provided: - Contains - The field value must contain at least one of the strings. - Count - The field value must contain the specified number of items. - EndsWith - The field value must match at least one suffix. - FileHeader - The file must contain a comment header. - FilePath - The file path must exist. - Greater - The field value must be greater. - GreaterOrEqual - The field value must be greater or equal to. - HasDefaultValue - The object should not have the field or the field value is set to the default value. - HasField - The object must have any of the specified fields. - HasFields - The object must have all of the specified fields. - HasFieldValue - The object must have the specified field and that field is not empty. - HasJsonSchema - The object must reference a JSON schema with the `$schema` field. - In - The field value must be included in the set. - IsArray - The field value must be an array. - IsBoolean - The field value must be a boolean. - IsDateTime - The field value must be a DateTime. - IsInteger - The field value must be an integer. - IsLower - The field value must include only lowercase characters. - IsNumeric - The field value must be a numeric type. - IsString - The field value must be a string. - IsUpper - The field value must include only uppercase characters. - JsonSchema - The object must validate successfully against a JSON schema. - Less - The field value must be less. - LessOrEqual - The field value must be less or equal to. - Like - The value must match any of the specified wildcard values. - Match - The field value matches a regular expression pattern. - NotContains - The value must not contain any of the specified strings. - NotCount - The field value must not contain the specified number of items. - NotEndsWith - The value must not end with any of the specified strings. - NotHasField - The object must not have any of the specified fields. - NotIn - The field value must not be included in the set. - NotLike - The value must not match any of the specified wildcard values. - NotMatch - The field value does not match a regular expression pattern. - NotNull - The field value must not be null. - NotStartsWith - The value must not start with any of the specified strings. - NotWithinPath - The field must not be within the specified path. - Null - The field value must not exist or be null. - NullOrEmpty - The object must not have the specified field or it must be empty. - TypeOf - The field value must be of the specified type. - SetOf - The field value must match a set of specified values. - StartsWith - The field value must match at least one prefix. - Subset - The field value must include a set of specified values. - Version - The field value must be a semantic version string. - WithinPath - The field value must be within the specified path. The `$Assert` variable can only be used within a rule definition block or script pre-conditions. USING ASSERTION METHODS An assertion method can be used like other methods in PowerShell. i.e. `$Assert.methodName(parameters)`. Assertion methods use the following standard pattern: - The first parameter is always the input object of type `PSObject`, additional parameters can be included based on the functionality required by the method. - In many cases the input object will be `$TargetObject`, however assertion methods must not assume that `$TargetObject` will be used. - Assertion methods must accept a `$Null` input object. - Assertion methods return the `AssertResult` object that is interpreted by the rule pipeline. Some assertion methods may overlap or provide similar functionality to built-in keywords. Where you have the choice, use built-in keywords. Use assertion methods for advanced cases or increased flexibility. In the following example, `Assert.HasFieldValue` asserts that `$TargetObject` should have a field named `Type` with a non-empty value. Rule 'Assert.HasTypeField' { $Assert.HasFieldValue($TargetObject, 'Type') } To find perform multiple assertions use. Rule 'Assert.HasRequiredFields' { $Assert.HasFieldValue($TargetObject, 'Name') $Assert.HasFieldValue($TargetObject, 'Type') $Assert.HasFieldValue($TargetObject, 'Value') } FIELD NAMES Many of the built-in assertion methods accept an object path or field name. An object path is an expression that traverses object properties, keys or indexes of the input object . The syntax for an object path is inspired by JSONPath which is current an IETF Internet-Draft. The object path expression can contain: - Property names for PSObjects or .NET objects. - Keys for hash table or dictionaries. - Indexes for arrays or collections. - Queries that filter items from array or collection properties. For example: - `.`, or `$` refers to input object itself. - `Name`, `.Name`, or `$.Name` refers to the name member of the input object . - `Properties.enabled` refers to the enabled member under the Properties member. Alternatively this can also be written as `Properties['enabled']`. - `Tags.env` refers to the env member under a hash table property of the input object . - `Tags+env` refers to the env member using a case-sensitive match. - `Properties.securityRules[0].name` references to the name member of the first security rule. - `Properties.securityRules[-1].name` references to the name member of the last security rule. - `Properties.securityRules[?@direction == 'Inbound'].name` returns the name of any inbound rules. This will return an array of security rule names. Notable differences between object paths and JSONPath are: - Member names (properties and keys) are case-insensitive by default. To perform a case-sensitive match of a member name use a plus selector `+` in front of the member name. Some assertions such as `HasField` provide an option to match case when matching member names. When this is used, the plus selector perform an case-insensitive match. - Quoted member names with single or double quotes are supported with dot selector. i.e. `Properties.'spaced name'` is valid. - Member names with a dash `-` are supported without being quoted. However member names can not start or end with a dash. i.e. `Properties.dashed-name` and `Properties.'-dashed-name'` are valid. CONTAINS The `Contains` assertion method checks the field value contains the specified string. Optionally a case-sensitive compare can be used, however case is ignored by default. The following parameters are accepted: - `inputObject` - The object being checked for the specified field. - `field` - The name of the field to check. This is a case insensitive compare. - `text` - A string or an array of strings to compare the field value with. Only one string must match. When an empty array of strings is specified or text is an empty string, `Contains` always passes. - `caseSensitive` (optional) - Use a case sensitive compare of the field value. Case is ignored by default. Reasons include: - The parameter 'inputObject' is null. - The parameter 'field' is null or empty. - The parameter 'text' is null. - The field '{0}' does not exist. - The field value '{0}' is not a string. - The field '{0}' does not contain '{1}'. Examples: Rule 'Contains' { $Assert.Contains($TargetObject, 'ResourceGroupName', 'prod') $Assert.Contains($TargetObject, 'Name', @('prod', 'test'), $True) } COUNT The `Count` assertion method checks the field value contains the specified number of items. The field value must be an array or collection. The following parameters are accepted: - `inputObject` - The object being checked for the specified field. - `field` - The name of the field to check. This is a case insensitive compare. - `count` - The number of items that the field value must contain. Reasons include: - The parameter 'inputObject' is null. - The parameter 'field' is null or empty. - The field '{0}' does not exist. - The field '{0}' is not enumerable. - The field '{0}' has '{1}' items instead of '{2}'. Examples: Rule 'Count' { $Assert.Count($TargetObject, 'items', 2) } ENDSWITH The `EndsWith` assertion method checks the field value ends with the specified suffix. Optionally a case-sensitive compare can be used, however case is ignored by default. The following parameters are accepted: - `inputObject` - The object being checked for the specified field. - `field` - The name of the field to check. This is a case insensitive compare. - `suffix` - A suffix or an array of suffixes to compare the field value with. Only one suffix must match. When an empty array of suffixes is specified or suffix is an empty string, `EndsWith` always passes. - `caseSensitive` (optional) - Use a case sensitive compare of the field value. Case is ignored by default. Reasons include: - The parameter 'inputObject' is null. - The parameter 'field' is null or empty. - The parameter 'suffix' is null. - The field '{0}' does not exist. - The field value '{0}' is not a string. - The field '{0}' does not end with '{1}'. Examples: Rule 'EndsWith' { $Assert.EndsWith($TargetObject, 'ResourceGroupName', 'eus') $Assert.EndsWith($TargetObject, 'Name', @('db', 'web'), $True) } FILEHEADER The `FileHeader` assertion method checks a file for a comment header. When comparing the file header, the format of line comments are automatically detected by file extension. Single line comments are supported. Multi-line comments are not supported. The following parameters are accepted: - `inputObject` - The object being checked for the specified field. - `field` - The name of the field containing a valid file path. - `header` - One or more lines of a header to compare with file contents. - `prefix` (optional) - An optional comment prefix for each line. By default a comment prefix will automatically detected based on file extension. When set, detection by file extension is skipped. Prefix detection for line comments is supported with the following file extensions: - `.bicep`, `.cs`, `.csx` `.ts`, `.js`, `.jsx`, `.fs`, `.go`, `.groovy`, `.php`, `.cpp`, `.h`, `.java`, `.json`, `.jsonc`, `.scala`, `Jenkinsfile` - Use a prefix of (`// `). - `.ps1`, `.psd1`, `.psm1`, `.yaml`, `.yml`, `.r`, `.py`, `.sh`, `.tf`, `.tfvars`, `.gitignore`, `.pl`, `.rb`, `Dockerfile` - Use a prefix of (`# `). - `.sql`, `.lau` - Use a prefix of (`-- `). - `.bat`, `.cmd` - Use a prefix of (`:: `). Reasons include: - The parameter 'inputObject' is null. - The parameter 'field' is null or empty. - The field '{0}' does not exist. - The field value '{0}' is not a string. - The file '{0}' does not exist. - The header was not set. Examples: Rule 'FileHeader' { $Assert.FileHeader($TargetObject, 'FullName', @( 'Copyright (c) Microsoft Corporation.' 'Licensed under the MIT License.' )); } FILEPATH The `FilePath` assertion method checks the file exists. Checks use file system case-sensitivity rules. The following parameters are accepted: - `inputObject` - The object being checked for the specified field. - `field` - The name of the field containing a file path. - `suffix` (optional) - Additional file path suffixes to append. When specified each suffix is combined with the file path. Only one full file path must be a valid file for the assertion method to pass. Reasons include: - The parameter 'inputObject' is null. - The parameter 'field' is null or empty. - The field '{0}' does not exist. - The field value '{0}' is not a string. - The file '{0}' does not exist.

The following parameters are accepted: - `inputObject` - The object being checked for the specified field. - `field` - The name of the field to check. This is a case insensitive compare. - `suffix` - A suffix or an array of suffixes to compare the field value with. When an empty array of suffixes is specified or suffix is an empty string, `NotEndsWith` always passes. - `caseSensitive` (optional) - Use a case sensitive compare of the field value. Case is ignored by default. Reasons include: - The parameter 'inputObject' is null. - The parameter 'field' is null or empty. - The parameter 'suffix' is null. - The field '{0}' does not exist. - The value '{0}' ends with '{1}'.

The following parameters are accepted: - `inputObject` - The object being checked for the specified field. - `field` - The name of one or more fields to check. By default, a case insensitive compare is used. If more than one field is specified, all must not exist. - `caseSensitive` (optional) - Use a case sensitive compare of the field name. Reasons include: - The parameter 'inputObject' is null. - The parameter 'field' is null or empty. - The field '{0}' exists.

Checks use file system case-sensitivity rules by default. The following parameters are accepted: - `inputObject` - The object being checked for the specified field. - `field` - The name of the field containing a file path. When the field is `InputFileInfo` or `FileInfo`, PSRule will automatically resolve the file path. - `path` - An array of one or more directory paths to check. Only one path must match. - `caseSensitive` (optional) - Determines if case-sensitive path matching is used. This can be set to `$True` or `$False`.

Examples: Rule 'Subset' { $Assert.Subset($TargetObject, 'logs', @('cluster-autoscaler', 'kube-apiserver', 'kube-scheduler'), $True, $True) } VERSION The `Version` assertion method checks the field value is a valid semantic version. A constraint can optionally be provided to require the semantic version to be within a range. The following parameters are accepted: - `inputObject` - The object being checked for the specified field. - `field` - The name of the field to check. This is a case insensitive compare. - `constraint` (optional) - A version constraint, see below for details of version constrain format. - `includePrerelease` (optional) - Determines if prerelease versions are included. Unless specified this defaults to `$False`. The following are supported constraints: - `version` - Must match version exactly. This also accepts the following prefixes; `=`, `v`, `V`. - e.g. `1.2.3`, `=1.2.3` - `>version` - Must be greater than version. - e.g. `>1.2.3` - `>=version` - Must be greater than or equal to version. - e.g. `>=1.2.3` - `<version` - Must be less than version. - e.g. `<1.2.3` - `<=version` - Must be less than or equal to version. - e.g. `<=1.2.3` - `^version` - Compatible with version. - e.g. `^1.2.3` - `>=1.2.3`, `<2.0.0` - `~version` - Approximately equivalent to version - e.g. `~1.2.3` - `>=1.2.3`, `<1.3.0` An empty, null or `*` constraint matches all valid semantic versions. Multiple constraints can be joined together: - Use a space to separate multiple constraints, each must be true ( logical AND ). - Separates constraint sets with the double pipe `||`. Only one constraint set must be true ( logical OR ). By example: - `1.2.3 || >=3.4.5 <5.0.0` results in: - Pass: `1.2.3`, `3.4.5`, `3.5.0`, `4.9.9`. - Fail: `3.0.0`, `5.0.0`. Handling for prerelease versions: - Constraints and versions containing prerelease identifiers are supported. i.e. `>=1.2.3-build.1` or `1.2.3-build.1`. - A version containing a prerelease identifer follows semantic versioning rules. i.e. `1.2.3-alpha` < `1.2.3-alpha.1` < `1.2.3-alpha.beta` < `1.2.3-beta` < `1.2.3-beta.2` < `1.2.3-beta.11` < `1.2.3-rc.1` < `1.2.3`. - A constraint without a prerelease identifer will only match a stable version by default. Set `includePrerelease` to `$True` to include prerelease versions. - Constraints with a prerelease identifer will only match: - Matching prerelease versions of the same major.minor.patch version by default. Set `includePrerelease` to `$True` to include prerelease versions of all matching versions. Alternatively use the `@pre` or `@prerelease` flag in a constraint. - Matching stable versions. By example: - `>=1.2.3` results in: - Pass: `1.2.3`, `9.9.9`. - Fail: `1.2.3-build.1`, `9.9.9-build.1`. - `>=1.2.3-0` results in: - Pass: `1.2.3`, `1.2.3-build.1`, `9.9.9`. - Fail: `9.9.9-build.1`. - `<1.2.3` results in: - Pass: `1.2.2`, `1.0.0`. - Fail: `1.0.0-build.1`, `1.2.3-build.1`. - `<1.2.3-0` results in: - Pass: `1.2.2`, `1.0.0`. - Fail: `1.0.0-build.1`, `1.2.3-build.1`. - `@pre >=1.2.3` results in: - Pass: `1.2.3`, `9.9.9`, `9.9.9-build.1` - Fail: `1.2.3-build.1`. - `@pre >=1.2.3-0` results in: - Pass: `1.2.3`, `1.2.3-build.1`, `9.9.9`, `9.9.9-build.1`. Reasons include: - The parameter 'inputObject' is null. - The parameter 'field' is null or empty. - The field '{0}' does not exist. - The field value '{0}' is not a version string. - The version '{0}' does not match the constraint '{1}'. Examples: Rule 'ValidVersion' { $Assert.Version($TargetObject, 'version') } Rule 'MinimumVersion' { $Assert.Version($TargetObject, 'version', '>=1.2.3') } Rule 'MinimumVersionWithPrerelease' { $Assert.Version($TargetObject, 'version', '>=1.2.3-0', $True) } Rule 'MinimumVersionWithFlag' { $Assert.Version($TargetObject, 'version', '@pre >=1.2.3-0') } WITHINPATH The `WithinPath` assertion method checks if the file path is within a required path. Checks use file system case-sensitivity rules by default. The following parameters are accepted: - `inputObject` - The object being checked for the specified field. - `field` - The name of the field containing a file path. When the field is `InputFileInfo` or `FileInfo`, PSRule will automatically resolve the file path. - `path` - An array of one or more directory paths to check. Only one path must match. - `caseSensitive` (optional) - Determines if case-sensitive path matching is used. This can be set to `$True` or `$False`. When not set or `$Null`, the case-sensitivity rules of the working path file system will be used. Reasons include: - The parameter 'inputObject' is null. - The parameter 'field' is null or empty. - The parameter 'path' is null or empty. - The field '{0}' does not exist. - The file '{0}' is not within the path '{1}'. Examples: Rule 'WithinPath' { # Require the file to be within either policy/ or security/ sub-directories. $Assert.WithinPath($TargetObject, 'FullName', @('policy/', 'security/')); } ADVANCED USAGE The `AssertResult` object returned from assertion methods: - Handles pass/ fail conditions and collection of reason information. - Allows rules to implement their own handling or forward it up the stack to affect the rule outcome. The following properties are available: - `Result` - Either `$True` (Pass) or `$False` (Fail). The following methods are available: - `AddReason(<string> text)` - Can be used to append additional reasons to the result. A reason can only be set if the assertion failed. Reason text should be localized before calling this method. Localization can be done using the `$LocalizedData` automatic variable. - `WithReason(<string> text, <bool> replace)` - Can be used to append or replace reasons on the result. In addition, `WithReason` can be chained. - `Reason(<string> text, params <object[]> args)` - Replaces the reason on the results with a formatted string. This method can be chained. For usage see examples below. - `ReasonFrom(<string> path, <string> text, params <object[]> args)` - Replaces the reason on the results with a formatted string. Path specifies the object path that affected the reason. This method can be chained. For usage see examples below. - `ReasonIf(<bool> condition, <string> text, params <object[]> args)` - Replaces the reason if the condition is true. This method can be chained, similar to `Reason`. - `ReasonIf(<string> path, <bool> condition, <string> text, params <object[]> args)` - Replaces the reason if the condition is true. This method can be chained, similar to `ReasonFrom`. - `PathPrefix(<string> path)` - Adds a path prefix to any reasons. This method can be chained. For usage see examples below. - `GetReason()` - Gets any reasons currently associated with the failed result. - `Complete()` - Returns `$True` (Pass) or `$False` (Fail) to the rule record. If the assertion failed, any reasons are automatically added to the rule record. To read the result without adding reason to the rule record use the `Result` property. - `Ignore()` - Ignores the result. Nothing future is returned and any reasons are cleared. Use this method when implementing custom handling. Use of `Complete` is optional, uncompleted results are automatically completed after the rule has executed. Uncompleted results may return reasons out of sequence. Using these advanced methods is not supported in rule script pre-conditions. In this example, `Complete` is used to find the first field with an empty value. Rule 'Assert.HasFieldValue' { $Assert.HasFieldValue($TargetObject, 'Name').Complete() -and $Assert.HasFieldValue($TargetObject, 'Type').Complete() -and $Assert.HasFieldValue($TargetObject, 'Value').Complete() } In this example, the built-in reason is replaced with a custom reason, and immediately returned. The reason text is automatically formatted with any parameters provided. Rule 'Assert.HasCustomValue' { $Assert. HasDefaultValue($TargetObject, 'value', 'test'). Reason('The field {0} is using a non-default value: {1}', 'value', $TargetObject.value) # With localized string $Assert. HasDefaultValue($TargetObject, 'value', 'test'). Reason($LocalizedData.NonDefaultValue, 'value', $TargetObject.value) } In this example, the built-in reason has a path prefix added to any reasons. Rule 'Assert.ChildHasFieldValue' { $items = @($TargetObject.items) for ($i = 0; $i -lt $items.Length; $i++) { $Assert.HasFieldValue($items[$i], 'Name').PathPrefix("items[$i]") } } DOWNSTREAM ISSUES Before PSRule performs analysis external tools or rules modules may have already performed analysis. Issues identified by downstream tools can be consumed by PSRule using the `_PSRule.issue` property. If a `_PSRule` property exists with `issue` sub-property PSRule will consume `issue` as an array of issues. Each issue has the following properties: - `type` - The issue type. Issues are filtered by type. - `name` - The name of a specific issue. - `message` - The reason message for the issue. To get issues for an object use the `Get` or `Any` methods. # Get an array of all issues for the current object. $PSRule.Issue.Get(); # Get an array of issues of a specific type. $PSRule.Issue.Get('CustomIssue'); # Return true of any issues exist. $PSRule.Issue.Any(); # Return true of any issues of a specific type exist. $PSRule.Issue.Any('CustomIssue'); For example: # Synopsis: Fail if the object has any 'PSRule.Rules.Azure.Parameter.Insecure' issues. Rule 'IssueReportTest' { $Assert.Create($PSRule.Issue.Get('PSRule.Rules.Azure.Parameter.Insecure')); } AUTHORING ASSERTION METHODS The following built-in helper methods are provided for working with `$Assert` when authoring new assertion methods: - `Create(<bool> condition, <string> reason, params <object[]> args)` - Returns a result either pass or fail assertion result. Additional arguments can be provided to format the custom reason string. - `Create(<TargetIssueInfo[]>)` - Returns a result based on reported downstream issues. - `Pass()` - Returns a pass assertion result. - `Fail()` - Results a fail assertion result. - `Fail(<string> reason, params <object[]> args)` - Results a fail assertion result with a custom reason. Additional arguments can be provided to format the custom reason string. AGGREGATING ASSERTION METHODS The following built-in helper methods are provided for aggregating assertion results: - `AnyOf(<AssertResult[]> results)` - Results from assertion methods are aggregated into a single result. If any result is a pass, the result is a pass. If all results are fails, the result is a fail and any reasons are added to the result. If no results are provided, the result is a fail. - `AllOf(<AssertResult[]> results)` - Results from assertion methods are aggregated into a single result. If all results are passes, the result is a pass. If any result is a fail, the result is a fail and any reasons are added to the result. If no results are provided, the result is a fail. For example: Rule 'Assert.HasFieldValue' { $Assert.AllOf( $Assert.HasFieldValue($TargetObject, 'Name'), $Assert.HasFieldValue($TargetObject, 'Type'), $Assert.HasFieldValue($TargetObject, 'Value') ) } NOTE An online version of this document is available at https://microsoft.github.io/PSRule/v2/concepts/PSRule/en-US/about_PSRule_Assert/.
