QUESTION
I've started to create UI tests for my PyQt5 widgets using QtTest but have run into the following difficulties:
In order to speed up things, some of my widgets only perform operations when visible. As it seems that QtTest runs with invisible widgets, the corresponding tests fail.
For the same reason, I cannot test program logic that makes a subwidget visible under certain conditions.
Is there a way to make widgets visible during test? Is this good practice (e.g. w.r.t. CI test on GitHub) and is QtTest the way to go?
I have tried to use pytest with pytest-qt without success as I couldn't find a proper introduction or tutorial and I do know "Test PyQt GUIs with QTest and unittest".
Below you find a MWE consisting of a widget mwe_qt_widget.MyWidget
with a combobox, a pushbutton and a label that gets updated by the other two subwidgets:

Answered 2021-Jun-15 at 17:01The problem is simple: QWidgets are hidden by default so isVisible() will return false, the solution is to invoke the show() method in init() to make it visible:

What is the purpose of using the =>
operator with public fields in a C# class? I saw this being done in the unit test code in the eShopOnWeb ASP.NET Core project hosted on GitHub. Is it actually a property with the =>
operator referring to the value returned from the getter method? The code in question is shown below:

QUESTION
I have a Room database in my application with one table containing received and sent messages. Inside of the table, the messages are just differentiated by the phone number, being null for the backend-server (since a server has no phone number) and the phone number of the user for the sent messages. (Entered on app installation, just as Whatsapp.) To sync the table with the backend, I introduced a new column, containing the backend id of the messages on the server. Since the server seperates sent and received messages (due to different information contained in the tables backend), the id of a sent message and the id of a received message can be equal, only distinguishable by the corresponding phone number. (Either null or own) So I created a unique constraint over both columns: backend_id & phone number.

Answered 2021-Jun-11 at 01:11In SQLite (and others that conform to SQL-92) null is considered different to any other null and hence your issue.
As such you should not be using null. You can overcome this setting the default value to a specific value that indicates a no supplied value.
For example you could use:-

QUESTION
I have made an Azure DevOps YAML Pipeline which successfully deploys into our testing env; I have copied that pipeline changed the App Name for our Staging Env and the Pipeline fails and gives out this error:
...ANSWER
Answered 2021-Jun-04 at 12:49I figured this out, there was a settings.xml file in wwwroot/site/deployments/ with the old branch details on it. If you delete settings.xml it will let go of that branch. You may not be able to delete the file though because its set to read-only permission and what you have to do is go into the configuration settings of your web app and change WEBSITE_RUN_FROM_PACKAGE value to 0, save that refresh the web app and then you will be able to delete the file. Then you can re-run the pipeline until your heart is content. :)
QUESTION
Open Telemetry InMemorySpanExporter
not resetting after test class is complete. This is causing span_list = self.memory_exporter.get_finished_spans()
to be empty for the 2nd test class.
ANSWER
Answered 2021-Jun-03 at 19:32Your description was not clear but I can share why you are running into AssertionError
. This is happening because we don't allow setting global tracer provider once it is already set; link to code which does that. There can only be one global tracer provider. So, when the call to trace.set_tracer_provider
made in second test it logs warning without doing anything hence your second attempt to set pipeline was unsuccessful i.e second exporter never received the spans.
