Test: Integration test for successful app start

[clstaudt]

First attempt: This is not yet working since the app process does not terminate.

def test_app_starts_and_quits():
    # Start the app process
    app_process = subprocess.Popen(["python", "app/app.py"])
    
    # Wait for a few seconds to let the app start
    time.sleep(3)
    
    # Verify the process is still running
    assert app_process.poll() is None
    
    # Terminate the app process
    app_process.terminate()
    
    # Wait for the process to end
    app_process.wait()
    
    # Verify the process has ended

    assert app_process.returncode is not None

urllib.error.HTTPError: HTTP Error 404: Not Found

i am getting this error while running your "python app/app.py" command in python virtual env

Hi @AmanSal1, could you please open a separate issue to tell us more about the error you are seeing:

• the full terminal output, including your command
• the steps you took to install the app

Thanks!

[AmanSal1]

@clstaudt compiled it !! now working fine

would work on your bug now

[AmanSal1]

can you explain in brief about the the issue ?
like you want to implement this fuction ??

Good news @AmanSal1

We welcome your contribution. The task is to implement a test that tests whether the app starts and quits successfully, as part of the test suite in tuttle_tests.

Here's how you can proceed:

1. have a look at the unit test suite, run it with pytest and check that everything is green
2. add a new test module tuttle_tests/test_app.py
3. add a function test_app_starts_and_quits and start developing

Here's how to contribute:

1. work on a new branch branching off the dev branch (e.g. test-app)
2. create a new pull request for that branch
3. mark it as draft as long as it is unfinished
4. assign me as a reviewer if ready
5. ask me anything in the discussion of the pull request if you need support

@clstaudt as if now there is no module to test that the app starts and quits successfully,so we have to implement a function to check it ? right ?

[clstaudt]

@AmanSal1 Correct, currently there is no test in the test suite that would catch any error that prevents the app from starting.

The test suite is run via the GitHub CI pipeline after every commit - which then shows ✅ or ❌.

[AmanSal1]

Sorry to disturb you again and again but i am bit confused because as i tried to comment out build method in app.py and then run it so it gave me an error .
so basically it is show which module is preventing to start the app

so exatly what do you want ?

[clstaudt]

@AmanSal1 A unit test that would fail on such an error would be great.

Also, any test that fails when the app fails to start properly.
