# eth2.0-spec-test-util

Mocha / Chai utility for interacting with eth2.0 spec tests

## API



### describeSpecTest

Run yaml Eth2.0 spec tests for a certain function
Compares actual vs expected for all test cases

#### Parameters

-   `testYamlPath` **[string](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/String)** path to yaml spec test
-   `testFunc` **[Function](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Statements/function)** function to use to generate output
-   `getInput` **[Function](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Statements/function)** function to convert test case into input array (optional, default `testCase=>testCase.input`)
-   `getExpected` **[Function](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Statements/function)** function to convert test case into a comparable expected output (optional, default `testCase=>testCase.output`)
-   `getActual` **[Function](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Statements/function)** function to convert function output into comparable actual output (optional, default `result=>result`)
-   `shouldError` **[Function](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Statements/function)** function to convert test case into a boolean, if the case should result in an error (optional, default `(testCase,index,testSpec)=>false`)
-   `shouldSkip` **[Function](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Statements/function)** function to convert test case into a boolean, if the case should be skipped (optional, default `(testCase,index,testSpec)=>false`)
-   `expectFunc` **[Function](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Statements/function)** function to run expectations against expected and actual output (optional, default `(testCase,expect,expected,actual)=>expect(actual).to.be.equal(expected)`)

An input argument to this GitHub Action is being exported as an environment variable. If a user of this action passes untrusted input, it could be used in an insecure manner by subsequent workflow steps.

What are GitHub Actions taint flows?

GitHub Actions: Input argument exported as environment variable

An input argument to this GitHub Action is being passed back as an output. If a user of this action passes untrusted input, it could be used in an insecure manner by consuming workflows.
