making pytests run reliably in vscode and powershell script to spin off a test file quickly

The concern is documenting ensuring pytest works as expected in vscode

1. requirements

• there is 1 codeFile and 1 testFile
• testFile is called *_test.py
• test is called test_foo()
• the only allowed separator on file (module) name is underscore _
• no dots
• no dashes
• do not have code and tests in same file (I used to do that for katas, etc.)
• you can use ptw for real-time testing there if needed

2. usage

• have a custom keyboard shortcut for opening the test sidebar
• CTRL + ALT + SHIFT + T
• possibly also for running a particular test method / debug particular test method

3. creating code

• lazy to keep creating an extra test file for each code file
• now, I am ignoring the recommended folder structure at this moment

function create-pythonFiles($name) {
    $codeFile = ("$name" -replace "\s", "_") -replace ".+", "$&.py"
    $testFile = ("$name" -replace "\s", "_") -replace ".+", "$&_test.py"
    New-Item $codeFile
    New-Item $testFile
    vsc .
    Invoke-Item $codeFile
    Invoke-Item $testFile
}
