If a test fails and Codeception was run with --debug the last 6 executed steps are displayed. Starting with the headline "Scenario Steps".
As far as I can see this number is defined in: src/Codeception/Subscriber/Console.php protected $traceLength = 5;. Is there any way to increase the number to show more steps?
We extracted some commonly used functionality to Tester classes which leads to some cases where only steps from that Tester class are shown making it harder to find out where in the test this error occurred.

The problem
I am currently running Robot Framework test cases with a target HW. During the Test Setup, I am flashing the software under test (firmware) to the target device. Due to several reasons, the flashing of the firmware fails sometimes, which causes the whole test case to fail. This is currently preventing me from getting any further meaningful results.
What I want to achieve
I want to detect when the test case fails in a particular Robot keyword during Test Setup. If a test case fails during a particular Test Setup keyword, I will retry/rerun the test case with a different target HW (I have my own Python script that executes the Robot runner with a given target device).
The main problem is that I don't know how to detect when a test case failed in a Test Setup keyword.
What I tried so far
My first guess was that this could be achieved by parsing the output.xml file, but I couldn't extract this information from there.
I have already considered retrying the flashing operation in Test Setup, but this won't work for me. The test case needs to be restarted from scratch (running in a different target HW).
Lastly, using "Run Keyword And Ignore Error" is not a solution neither since Test Setup must be run successfully in order to continue the test case.
The best solution I found so far: how to list all keywords used by a robotframework test suite
from robot.api import ExecutionResult, ResultVisitor
result = ExecutionResult('output.xml')
class MyVisitor(ResultVisitor):
def visit_keyword(self, kw):
print("Keyword Name: " + str(kw.name))
print("Keyword Status: " + str(kw.status))
result.visit(MyVisitor())
Output:
Keyword Name: MyKeywords.My Test Setup
Keyword Status: FAIL
Where is possible to see the list of tests marked as FLAKY from firebase test LAB?
I'm using:
functions.testLab.testMatrix().onComplete(testMatrix => {})
to receive the TestMatrix object and
--num-flaky-test-attempts=int
because they say:
Specifies the number of times a test execution should be reattempted if one or more of its test cases fail for any reason. An execution that initially fails but succeeds on any reattempt is reported as FLAKY.
In the documentation there is this part:
But there is no reference to the test marked as Flaky.
Where we can see the list of tests flaky?
In the TestMatrix object received as an output on onComplete, there is also no reference for flaky tests.
Unfortunately, flaky outcome is not reported at the matrix level at this point.
The flaky results are shown in History, Device, and Test Case views.

I have a series of tests that are dependent on a step in the middle (such as creating an account). The API that I'm using for this is a kind of brittle (which is a separate problem), and sometimes fails. I'd like to be able to just quit the tests in the middle there when that fails, instead of wait for TestCafe to fail the initial assertions for the next few tests that follow. Is there a way to get the test controller to stop, or signify to the fixture that the tests should stop? I immediately thought of Spock's #Stepwise annotation, but I can't find anything like that in the TestCafe docs.
The Stop on First Fail option stops the entire run once a failed test occurred. If I understand your scenario correctly, you could add an assertion for a successful account creation and if it fails, exit the entire run with this option.

We are trying to automate E2E test cases for an booking application which involves around 60+ steps for each test case. Whenever there is a failure at the final steps it is very much time consuming if we go for traditional retry option since the test case will be executed from step 1 again. On the application we have some logical steps which can be marked somehow through which we would like to achieve resuming the test case from a logical point before the failed step. Say for example, among the 60 steps say every 10th step is a logical point in which the script can be resumed instead of retrying from the step 1. say if the failure is on line number 43 then with the help of booking reference number the test can be resumed from step number 41 since the validation has been completed till step 40 (step 40 is a logical closure point). There might be an option you may suggest to split the test case into smaller modules, which will not work for me since it is an E2E test case for the application which we would want to have in a single Geb Spec. The framework is built using Geb & Spock for Web Application automation. Please share your thoughts / logics on how can we build the recovery scenarios for this case. Thanks for your support.!
As of now i am not able to find out any solution for this kind of problem.
Below are few things which can be done to achieve the same, but before we talk about the solutions, we should also talk about the issues which it will create. You are running E2E test cases and if they fail at step 10 then they should be started from scratch not from step 10 because you can miss important integration defects which are occurring when you perform 10th step after running first 9 steps. For e.g. if you create an account and then immediately search for hotel, you application might through error because its a newly created account, but if you retry it from a step where you are just trying to search for the hotel rooms then it might work, because of the time spent between your test failure and restarting the test, and you will not notice this issue.
Now if you must achieve this then
Create a log every time you reach a checkpoint, which can be a simple text file indicating the test case name and checkpoint number, then use retry analyzer for running the failed tests, inside the test look for the text file with the test case name, if it exists then simple skip the code to the checkpoint mentioned in the text file. It can be used in different ways, for e.g. if your e2e test if going through 3 applications then file can have the test case name and the last passed application name, if you have used page objects then you can write the last successful page object name in the text file and use that for continuing the test.
Above solution is just an idea, because I dont think there are any existing solutions for this issue.
Hope this will give you an idea about how to start working on this problem.
The possible solution to your problem is to first define the way in which you want to write your tests.
I would recommend considering one test Spec (class) as one E2E test containing multiple features.
Also, it is recommended to use opensource Spock Retry project available on GitHub, after implementing RetryOnFailure
your final code should look like:
#RetryOnFailure(times= 2) // times parameter is for retry attempts, default= 0
class MyEndtoEndTest1 extends GebReportingSpec {
def bookingRefNumber
def "First Feature block which cover the Test till a logical step"()
{
// your test steps here
bookingRefNumber = //assign your booking Ref here
}
def "Second Feature which covers a set of subsequent logical steps "()
{
//use the bookingRefNumber generated in the First Feature block
}
def "Third set of Logical Steps"()
{ // your test steps here
}
def "End of the E2E test "()
{ // Your final Test steps here
}
The passing of all the Feature blocks (methods) will signify a successful E2E test execution.
It sounds like your end to end test case is too big and too brittle. What's the reasoning behind needing it all in one script.
You've already stated you can use the booking reference to continue on at a later step if it fails, this seems like a logical place to split your tests.
Do the first bit, output the booking reference to a file. Read the booking reference for the second test and complete the journey, if it fails then a retry won't take anywhere near as long.
If you're using your tests to provide quick feedback after a build and your tests keep failing then I would look to split up the journey into smaller smoke tests, and if required run some overnight end to end tests with as many retries as you like.
The fact it keeps failing suggests your tests, environment or build is brittle.
I was wondering if there is a service where I could send data and then group that data however I want and later display it in charts or similar?
What I want to do is - start protractor e2e tests and let them run forever. Since some of the tests randomly fail I can not rely on them if they were included in main build. What I'm going to do is run tests in each supported browser over and over again and then capture which tests failed in which browser, if they passed - reset failure counter and so on.. That way I can monitor how my system is doing without wasting my time waiting for build to run successfully.
My data could look something like that:
{
testName: 'Path to test + name',
status: 'failed/passed',
browser: 'firefox/chrome/safari/opera...'
}
Now when test fails in (let's say) chrome over and over again I will see that it's error counter is constantly increasing, that means something is either wrong with system or I need to fix test in chrome.
Does anyone know service that could consume my data and display aggregated info?
