Likely unintended behavior change in commit 41424d5

[doublep]

Patterns are no longer treated as regexps because of these lines in 41424d5:

-      (buttercup--mark-skipped buttercup-suites patterns))
+      (buttercup-mark-skipped (regexp-opt patterns) t))

Function regexp-opt accepts strings not regexps.

In comparison, previously each pattern was treated as regexp:

-      (unless (cl-dolist (p patterns)
-                (when (string-match p spec-full-name)

Command line patterns are documented to be substrings, not regexps in the shell script help. That is probably not prominent enough.
Was this issue on the command line or through the api?

[doublep]

It's not really an issue, I just remember that it used to be regexp and noticed this suspicious change. If this is intentional (i.e. if it was behaving incorrectly before), it is not a problem, I will adjust Eldev accordingly then, so that Eldev/Buttercup behaves the same as Buttercup.

[doublep]

Basically, I need a clarification what the intended behavior is, because I cannot pass a list of strings to buttercup-mark-skipped for it to decide how to treat them.

[snogge]

So the change was intentional but probably a bad idea.
I chose to do this change to keep the code simpler, but didn't really gain much.
Please check if #192 works for you.

Yes, seems to work fine:

~/git/buttercup$ eldev test "raised?"
Running 14 out of 162 specs.

The buttercup-failed signal
can be raised (2.14ms)

The buttercup-pending signal
can be raised (0.21ms)

The `buttercup-expect' function
with a function as a matcher argument
should not raise an error if the function returns true (0.26ms)
should raise an error if the function returns false (0.21ms)
[...]

Ran 14 out of 162 specs, 0 failed, in 95.27ms.

Would you be interested in writing a section in the docs/running-tests.md file about using eldev with buttercup?
Maybe you want some stuff finished first?

[doublep]

Basically it would be a repeat of parts of Eldev's documentation, but if you want, I can do it.

Maybe you want some stuff finished first?

Currently missing (to bring Buttecup support in Eldev on par with Eldev) are #190 (trivial), #188 and also maybe #185 (this one should also be simple; if implemented, I will add support for this for both ERT and Buttercup in one go). Also maybe a way to reuse previous test results, but this would not be easy and would need to be designed first.
