This extension is a simple extension that shows how to define applicability of an extension part using document selector pattern. The extension emulates running unit tests on background when user opens any C# file under "tests" folder anywhere in solution.
UnitTestRunner is a part of the extension that listens for new editor text view creation and changes to open text views. This component monitors for events in C# files under "tests" folder anywhere in solution and when open or modified, it emulates running unit tests in these files by writing a message to the Output Window.
UnitTestRunner utilizes the AppliesTo configuration to indicate that it is interested in events from text views whose documents have .cs extension and are under "tests" folder anywhere in solution by using **/tests/*.cs glob pattern
/// <inheritdoc />
public TextViewExtensionConfiguration TextViewExtensionConfiguration => new()
{
AppliesTo = new[]
{
DocumentFilter.FromGlobPattern("**/tests/*.cs", relativePath: false),
},
};Even though this class implements 2 different contracts, a single instance of it will be created so that state can be shared between different editor components that interact together.
Once deployed, the Document Selector Sample will write Running unit tests in File.cs to the Output Window every time you open or modify C# file under "tests" folder anywhere in solution.
