QProcess and Windows runner on GitHub Actions

agarny

Hi,

I have some tests that I run using QProcess. I basically have something like this:

...

QProcess process;

process.setProcessChannelMode(QProcess::MergedChannels);
process.start(someTest, QStringList());
process.waitForFinished(-1);

std::cout << qPrintable(process.readAll()) << std::endl;

...

It's all working fine locally using Windows, Linux and macOS. However, I also want to run them using GitHub Actions and although it's fine on Linux and macOS, it's not on Windows. For whatever reason, on the GHA's Windows runner, QProcess::readAll() always returns an empty QByteArray. I have tried various things (e.g., https://devdreamz.com/question/225292-get-output-in-qt-qprocessstart-and-qprocessreadallstandardoutput), but to no avail.

Has someone else experienced the same with QProcess and GHA's Windows runner and, more importantly, found a way to get it to work?

Cheers, Alan.
