hi, is it possible to pass some arguments to the tests?

Yep:

companion object {
        @JvmStatic
        fun generateArguments() = listOf(
            Arguments.of(
                "bla bla bla",
             "bla bla bla"
            )
        )
}

@ParameterizedTest
    @MethodSource("generateArguments")
    fun fooTest(url: String, expected: String) {
        url.extension1 `should be equal to` expected
    }

is it possible to integrate it with CI?

Depends on your CI, but I think yes

GH action

Never used it, sorry!

what do you use?

Right now I'm using Bitrise and CircleCI, I've used also Jenkins and planning to use Github actions

I'm confused. This is a kotest channel, yet that code looks like JUnit5. Kotest supports both property based testing and data-driven testing (which is effectively what the above example is). https://github.com/kotest/kotest#check-all-the-tricky-cases-with-data-driven-testing

Data driven testing like @Mike says and in 4.0 you can use test factories for completely dynamic tests.

@sam can you help me? How can I pass arguments?

See the code samples in the docs. It's a slightly different format than JUnit as you construct the data table, and then iterate on the rows, but the docs are quite clear on how to use it. I linked to the docs above in the thread.
