test: unit tests for block type guards

[matthewlipski]

Summary

This PR adds unit tests for editorHasBlockWithType.

The code for editorHasBlockWithType has also been changed slightly - when checking for a block with a given propSchema and values, the values can be an unordered subset of the ones in the schema. Previously, the 2 arrays had to be identical in order for the type guard to return true.

Rationale

Needed for #2096 and useful in general.

Easy enough, just a nice to have case to add

[matthewlipski]

Also @YousefED we talked on call yesterday about whether to put additional tests in the tests directory or with the files that they're actually testing. Should we have the same discussion with @nperez0111 before merging this or is that for another time?

[YousefED]

approved.

do the fixes to the source file mean there were bugs in the implementation btw?

(created separate ticket for testing discussion)

[matthewlipski]

Yeah the !== undefined additions are to fix bugs, since things like empty strings set as default props would cause issues. Not sure if other change with values counts as a fix or not, it just makes it easier e.g. if you want to see if the textAlignment prop allows for "justify" alignment. You'd previously have to check with:

editorHasBlockWithType(editor, "paragraph", {
  textAlignment: {
    default: "left",
    values: ["left", "center", "right", "justify"]
  }
})

and now it's just:

editorHasBlockWithType(editor, "paragraph", {
  textAlignment: {
    default: "left",
    values: ["justify"]
  }
})

Cool, proofs the value of investing in these tests :) Op vr 17 okt 2025, 11:26 schreef Matthew Lipski ***@***.***>:
