Tests: Add missing tests for Format API code

[gziolo]

When working on #10209 we added a few unit tests. However, we could use them more to have much better coverage which should help us avoid regressions in the future.

We miss tests for the following:

Format API

• registerFormatType (similar to https://github.com/WordPress/gutenberg/blob/master/packages/blocks/src/api/test/registration.js#L52)
• unregisterFormatType (similar to https://github.com/WordPress/gutenberg/blob/master/packages/blocks/src/api/test/registration.js#L337)
• getFormatType (similar to https://github.com/WordPress/gutenberg/blob/master/packages/blocks/src/api/test/registration.js#L414)
• getFormatTypes (similar to https://github.com/WordPress/gutenberg/blob/master/packages/blocks/src/api/test/registration.js#L444)
• insertObject
• toggleFormat

RichText actions

• addFormatTypes
• removeFormatTypes

RichText selectors

• getFormatTypes
• getFormatType

I'll try to tackle this one!

[Pixelrobin]

I assume you mean getFormatType and getFormatTypes in the Format API section? They're also listed in the RichText selectors section.

[gziolo]

Yes, you are correct. Description updated.

I was able to successfully register a custom format in the editor, and I can confirm that it was registered successfully by running the code wp.richText.getFormatType in the console.

The formatting also works with the keyboard shortcut key I set it to, but unfortunately the button I've set for the formatting is not showing. Can you please provide like a brief process on how to register a format type and have it displayed as one of the formatting buttons on blocks?

We are working on documentation in #11105. Can you open a separate issue for your use case with the code snippet included so we could help you? This issue is meant to track progress on unit tests.

@Pixelrobin Are you still able to work on this?

[Pixelrobin]

@desrosj Yes, sorry, I got caught up in other things for a bit.

Opened PR #11562. Sorry for the wait, and the merge conflicts. It looks like you could just ignore my version of register-format-type in the tests?

This was my first Gutenberg PR and first time using Jest, so I learned a lot 😄, thanks for that opportunity. I hope it's good to go!

@Pixelrobin great work, I will take a closer look later today 👍

No worries, I will see if we can cherry-pick some of your tests from this file.
