Checked in a local version of grails-functional-tests (UploadControllerSpec):

void "Test file upload"() {
        when: "When go to an upload page"
        go "/upload/index"

        copyFileToContainer(Transferable.of("Test upload", 0777), "/test.txt")
        def form = $('#myForm')

        form.myFile = "/test.txt"
        $('#input1').click()

        then:"The file is uploaded"
        $('p').text() == 'Test upload'
    }

where without the convenience methods a cast is needed:

(webDriverContainer as WebDriverContainer).copyFile...

is needed.

Excellent!
There are some unused imports and some whitespace on line 101.

@jdaugherty Can you confirm that it works on MacOS with Testcontainers.exposeHostPorts(serverPort) before start()?

[matrei]

@sbglasius Would it be benefitial to expose the container via:

    BrowserWebDriverContainer getContainer() {
        return webDriverContainer
    }

And then you can access all methods on the container in the tests, eg: container.execInContainer(...) instead of creating methods in ContainerGebSpec that just delegates?

[sbglasius]

Followed @matrei's suggestion, removed convenience methods and added getContainer() instead

[matrei]

Nice! Now there are some unused imports and a whitespace issue (Line 122) again.

If @jdaugherty, can confirm the MacOS fix, that should probably be in it's own PR or commit as it fixes a bug.

Otherwise, I'd say Squash and merge on the new feature!

[jdaugherty]

I'm working on confirming the change on MacOS, but I noticed the README.md still contains references to GebConfig.groovy. Isn't this need removed now?

[jdaugherty]

I can confirm the expose ports change fixes the MacOS issue.

[sbglasius]

the reference to GebConfig.groovy is relevant if you use GebSpec instead of ContainerGebSpec
