Hello Stackoverflow Community,

So I am trying to set environment vars for a database test in a vala project, but I can't find evidence of the variable anywhere. I also tried setting command line args but I couldnt access those either.

In my meson.build file:

test(test_db, test_db_exe, args : ['some_arg'], env : ['var1=some_env_arg'])

I then print out both my env vars and arguments with the following code:

 foreach (string va in GLib.Environment.list_variables()){
    GLib.Test.message(va);
}
foreach (string va in args){
    GLib.Test.message(va);
}

I don't see any evidence of these vars anywhere!

Here is the output of the test showing the environment variables and command line arguments printed to stdout:

You need to be looking in the meson-logs directory of your build directory. For my tests, stdout appears in testlog.txt.
