--grep is case insensitive in the mode "dry-run" whereas case sensitive in the mode "run"

[Jaromir Obr]

What are you trying to achieve?

I would expect that "run" and "dry-run" modes have the same behavior related to case-sensitivity of tags.
Personally I prefer case-insensitive tags so that I don't want to think if I need to pass the tag @problem or @Problem
https://codecept.io/advanced/#tags doesn't say anything about case sensitivity.

What do you get instead?

run is "case sensitive" when using --grep

$ codeceptjs run --grep @Problem
CodeceptJS v3.5.14 #StandWithUkraine
Using test root "/home/mirao/workspace/tmp"


  OK  | 0 passed   // 0ms

dry-run is "case insensitive" when using --grep

$ codeceptjs dry-run --grep @Problem
Tests from /home/mirao/workspace/tmp:

My @problem -- /home/mirao/workspace/tmp/My_test.ts -- 1 tests
  ☐ test something

  Total: 1 suites | 1 tests  

--- DRY MODE: No tests were executed ---

Provide test source code if related

Feature('My').tag("@problem");

Scenario('test something',  ({ I }) => {
    I.amOnPage('https://www.google.com');
});

When I'm passing the grep pattern, it doesn't return me anything.

I think --grep in the dry-run mode works only for tags at Feature().
Is it your case?

[KobeN]

Oh, really? I thought it is applicable to all. 😅

[Jaromir Obr]

It looks like --grep in the run mode is handled by mocha (RegExp) whereas --grep in the dry-run is handled by CodeceptJS itself.
