QUESTION
Hellow, i have pop-up window with 'select' element in chrome browser, i need to click this 'select' element in my ui-test scenario. It is on image: my web page
I am using c# and TechTalk.SpecFlow. I am trying to click it like this:
...ANSWER
Answered 2022-Apr-11 at 11:48A couple of suggestions. I would try suggestion 1 first. If that doesn't work, try suggestion 2 as well:
Don't Use Exact XPaths — I see this frequently. Use a combination of tag names, attributes and parent elements to make your locators more robust. In fact, the
tag has an Id. Use that. Id attributes must be unique in the HTML document (if they aren't, it is a bug that should be fixed): Browser.ClickWebElementNew("//select[@id = 'state']", FoundBy.XPath); This can help keep your tests passing when minor HTML changes are made in the future. Use An Explicit Wait — You will likely need this as well. You will need to wait for the element to be clickable. If using Selenium 3 or if you have the DotNetSeleniumExtras NuGet package installed, use ExpectedConditions in the ClickWebElementNew method: public void ClickWebElementNew(string findElement, FoundBy f) { var wait = new WebDriverWait(_chromeDriver, TimeSpan.FromSeconds(30)); By locator = null; if (f == FoundBy.XPath) { locator = By.XPath(findElement) } else if (f == FoundBy.CssSelector) { locator = By.CssSelector(findElement); } else { throw new InvalidOperationException("Unsupported FoundBy"); } var element = wait.Until(ExpectedConditions.ElementToBeClickable(locator)); element.Click(); } If using Selenium 4 and you don't have the DotNetSeleniumExtras package installed, this should work: var element = wait.Until(d => { d.FindElement(locator).Click(); return true; }); element.Click(); The main reason for "waiting for the element to be clickable" is because certain user interface animations prevent Selenium from interacting with elements. These can be subtle, but important. Any movement, or fade-in can cause issues with interacting with the page. If ideas 1 and 2 do not work, look to see if the element is inside a frame or iframe. You need to switch to the frame before interacting with its elements. Also look for elements that overlap that same region of the page. This can cause problems too, especially if running in headless mode and you are not setting a window size.
QUESTION
Hilt testing guide documentaton has this paragraph about Unit test
...Hilt isn't necessary for unit tests, since when testing a class that uses constructor injection, you don't need to use Hilt to instantiate that class. Instead, you can directly call a class constructor by passing in fake or mock dependencies, just as you would if the constructor weren't annotated:
ANSWER
Answered 2022-Apr-09 at 00:09With unit tests you verify behavior inside the classes, while in UI test you verify UI state given data. In unit test you don't need Hilt to generate a object tree, you are testing a small building unit of your app, a class, a function. Your unit test have limited scope of objects needed, so that's another reason why you don't need Hilt to build entire tree of objects each unit test.
In unit test you verify that an event have happened, a function has been called or a result has been returned given an input.
Hilt is injecting fake components in your UI test through which you are providing data that is rendered.
QUESTION
In the application, I am writing Espresso UI test for login flow in the app. I wrote the test and it works fine, but I have one case where I have problem.
In this application, users sometimes get bonuses when opening app (usually they don't but this is let's say 1:100 scenario) In these situations, the pop up appears on the screen and my test fails because my code tries to trigger the button that is not visible (it is under the pop up).
I would like to write if-else in a test where I can for example check the visibility of the pop up close button. So if this is visible click on it and if it's not, then continue normally.
But I didn't find any if-else syntax in UI testing. Can someone with more experience in UI espresso testing help me with some advice here? THanks
...ANSWER
Answered 2022-Mar-29 at 17:10Create two tests. One where bonus popup cannot appear and one where bonus popup always appears. This way so can test both behaviours.
You should not leave anything to a chance, and your issue is exactly the example of why not.
QUESTION
I am running a simple Test on LaunchedEffect:
...ANSWER
Answered 2022-Mar-28 at 09:35The box composable by default doesn't have any size so technically, when the user clicks on any portion of the screen, the event doesn't get consumed by the Box.
You can verify this by adding a background(color = Color.Green) modifier to your box and observe that no section of the screen gets colored green as expected.
You can fix this by setting a size modifier for your Box.
You can change your box implementation to this and it should work. I am using fillMaxSize here

I am having trouble getting Selenium TestContainers to record the tests for me.

ANSWER
Answered 2022-Mar-04 at 09:06Best-case I would love to be able to trigger recording in a standard junit @AfterEach method, but the arguments required (TestDescription description, Optional throwable) aren't available...
This is what I would recommend for more advanced framework integrations that don't work OOTB. You should be able instatiate a TestDescription for your use case e.g., from an anonymous class (it is used to infer the recording's file name).

I've created a fake urlprovider binding and annotated with TestInstallIN
...ANSWER
Answered 2022-Feb-14 at 04:50Thanks to Brad, the issue was with the AppModule, I was using Includes whereas hilt doesn't need Includes as it already has InstallIn annotation for this purpose. Once I remove it the UI test starts to work.

I'm trying to write a Karate UI test for my webpage which currently has a self signed certificate and hence blocked by the browser by default. According to the documentation, when acceptInsecureCerts parameter is enabled, this check should be bypassed. But I can't find the correct syntax to pass this parameter to the driver. This is my (simplified) feature file:

Answered 2021-Oct-15 at 12:41Hold on, chrome is NOT webdriver based, so the webDriverSession will not apply. It would for chromedriver.
I did a quick search and the best I could find is this: ignore-certificate-errors + headless puppeteer+google cloud
So not sure if this works:
QUESTION
I'm making UI tests for an application that scans barcodes. I've successfully found a way of inserting a barcode image in the emulator virtual scene to test scanning following this post.
I've made it following this answer since it was exactly what I needed: The problem is that I want to test different barcode images for each test case, and I'm trying to find a way of doing it.
An approach I've thought is replacing the image in real time, but I think you need to restart the emulator plus it looks dirty and I don't know how to implement it in kaspresso. Another way is injecting a fake result in the scanner, but then the purpose of end-to-end UI tests is lost so...
What would be the best approach to do this and implement it (if possible). I'm looking for answers but it seems no one has done it yet.
I've also sen there are macros in the resource folders in emulator folder, this may be useful but I don't know how to use them:
...ANSWER
Answered 2021-Sep-29 at 12:15In the end, I made a .jar file done in Java 8, that used sockets to manipulate the file I used as barcode using the .posters solution. It launched with a Gradle task when running the UI tests and in the android emulator, I used a client to communicate which barcode to place in the virtual scene. When the last test is run, the emulator closes the server. We can implement this in a pipeline.
