test: integration tests for main.js (actions#56)
Part of actions#43 This PR adds tests for [`main.js`](https://github.com/actions/create-github-app-token/blob/main/lib/main.js), similar to [the tests that already exist for `post.js`](https://github.com/actions/create-github-app-token/tree/main/tests). Specifically, it tests that: - `main` exits with an error when `GITHUB_REPOSITORY` is missing. - `main` exits with an error when `GITHUB_REPOSITORY_OWNER` is missing. - `main` successfully obtains a token when… - …the `owner` and `repositories` inputs are set (and the latter is a single repo). - …the `owner` and `repositories` inputs are set (and the latter is a list of repos). - …the `owner` input is set (to an org), but the `repositories` input isn’t set. - …the `owner` input is set (to a user), but the `repositories` input isn’t set. - …the `owner` input is not set, but the `repositories` input is set. - …neither the `owner` nor `repositories` input is set. ❧ Architecturally, in order to keep individual tests concise, this PR adds `tests/main.js`, which: - sets commonly-used inputs, environment variables, and mocks, then - calls a callback function that can edit the variables and add additional mocks, then - runs `main.js` itself. The `tests/main-token-get-*.test.js` test files run `tests/main.js` with various scenario-specific callback functions.
