[Question] How to wait for multiple responses ?

In js I can do this

    async waitForFindingUpload(findingName) {
        return await this.page.waitForResponse(async (response) => {
            const body = await response.text();
            return body.includes(findingName)
        });
    }
        const responses = await Promise.all([
            this.waitForFindingUpload("Name of Finding 1"),
            this.waitForFindingUpload("Name of Finding 2"),
            this.#uploadFile()
        ])

How to do the same in java ? Your API suggests this waiting mechanism:

        Response res = page.waitForResponse(response -> {
            return response.url().equals("https://url_/gateway/graphql") &&
                    response.request().postData().contains("sidebar");
        }, () -> {
            page.click("//button[@type='submit']");
        });

this way I can wait only for 1 response

I tried just several waiting in a row after click on a button:

page.click("//button[@type='submit']");
page.waitForResponse()
page.waitForResponse()
page.waitForResponse()
page.waitForResponse()
page.waitForResponse()

and not all of them are resolved. For example after page loaded there are 5 graphql responses, 3-4 consequent waits are resolved I guess based on timings.

You can have nested waitForResponse calls:

    Response response2 = page.waitForResponse(response -> {
      return response.url().contains("first.png");
    }, () -> {
      Response response1 = page.waitForResponse(response -> {
          return response.url().contains("second.html");
        },
        ()-> {
          page.click("//button[@type='submit']");
        });
    });

Or alternatively you can always use page.onResponse() that will be called for all responses.

Hope it answers your question.

thanks for this @yury-s . I had to make a small change to the if statement because it was throwing an index out of bounds exception. For anyone else reading this here is how I modified it:

    void checkAllResponses(List<String> urls, Runnable code, Page page) {
        if (urls.isEmpty()) {
            code.run();
        } else {
            String url = urls.remove(urls.size() - 1);
            Response response = page.waitForResponse(url, () -> checkAllResponses(urls, code, page));
            assertTrue(response.ok(), url);
        }
    }
