@batterii/generator-ts-test

A yeoman generator for creating integration test blocks in Batterii TypeScript projects.

Usage

  yo @batterii/ts-test [options]

Options:
  -h,   --help           # Print the generator's options and usage
        --skip-cache     # Do not remember prompt answers             Default: false
        --skip-install   # Do not automatically install dependencies  Default: false
        --force-install  # Fail on install dependencies error         Default: false
  -n,   --name           # Name for the test block
  -f,   --filename       # Name for the test file (no extension)

The Test Block Name

Like all mocha tests, integration tests must be placed in a describe block. When running this generator, use the --name option to provide the name of this block.

You can name the block whatever you like, but ideally it should provide some context for the tests that will go inside it. If the tests will be exercising the API of some public class, for example, you should name the block after that class. If, on the other hand, you're applying various API's to a particular use case, you should name it after that use case.

Only letters, digits, dashes, spaces, and underscores are allowed in the test block name, simply because this subset of characters is much easier to convert to a name for the file that will be created.

You can use the the --filename option to provide the name for the test file that will be created. If you provide it, you will want to omit the extension as .ts will be appended automatically. This will default to a name based on the test block name and should not usually need to be changed.

The Created Test File

When the generator has finished, a new file will have been created in the test/integration directory. The file's name will the same as the test block name, except converted to satisfy file naming conventions. The test block name will also have '(Integration)' appended to it in the actual describe block. Both of these measures are to ensure that tests are easy to find based on the mocha reporter output alone.

Write your tests inside the generated describe block, using the already-imported chai expect API.

What about Unit Tests?

Unlike integration tests, unit tests are directly associated with a particular class or static module, so unit test files do not have their own generator. To create them, use @batterii/generator-ts-class or @batterii/generator-ts-module.
