Add full support for parametrized tests

Environment

1. node -v: v11.10.0
2. npm -v: 6.7.0
3. npm ls jest: └── jest@24.1.0
4. Operating system: macOS Mojave

Prerequisite

• are you able to run jest test from command line? yes
• how do you run your tests from command line? (for example: npm run test or node_modules/.bin/jest) npm test

Expected Behavior

When using syntax test.each(table)(name, fn, timeout) described here test status circles show the status of tests and failed test error appears in-line.

Actual Behavior

When using syntax test.each(table)(name, fn, timeout) test status circles are not shown and test errors are not displayed inline.

Workaround

If applying parametrization to describe with describe.each, test status information seems to be showed correctly.

In the image below all three tests should have been marked as failed. As it can be seen, the second does not show any test status information and the third (workaround) seems to work. Since I don’t want to wrap all my separate tests into describe.each workaround is not that useful in my case.

@DScheglov I tried your snippet above and all seems to be fine:

Something else is at play here… which jest version your project is on? I should have mentioned that for parameterized tests to be properly reported, you need to have jest version >= 26.5.0 (see migration notes for alpha.3 release). Otherwise, can you post the relevant debug message from the developer console or OUTPUT channel?
