开关 --listTests 返回测试文件的 JSON 数组，然后退出(而不是运行测试).>

它可能不是您正在寻找的，因为它不解析describe/it 函数，输出也不是很漂亮.

Is it possible to get a list of suites/specs without running the actual tests w/ Jest.

For example, I have a test that looks like this:

describe('when blah blah blah', function () {
  it('returns foobar', function () { /* test code */ })
})

Ideally, I'd like to be able to just get a list of describe/it statements to quickly look at scenarios covered.

# stdout
when blah blah blah
  returns foobar

I think this is possible with rspec, using a dry-run flag. Is there any such option with Jest?

I took a look at the Jest CLI documentation and have done an issue search at the project's Github page, but could not find anything.

The switch --listTests returns a JSON array of the test files and then exits (instead of running the tests).

It might not be exactly what you're looking for though since it doesn't parse the describe/it functions, nor is the output very pretty.
