Advanced Logging

Prova provides a built-in logging abstraction that allows you to write structured logs from your tests. These logs are exposed via TestContext and can be captured by the test runner or custom reporters.

Usage

Access the logger via TestContext.Current.Logger:

using Prova;
using System.Threading.Tasks;

public class MyTests
{
    [Fact]
    public async Task ProcessData()
    {
        var logger = TestContext.Current.Logger;
        
        logger.Log("Starting processing...");
        
        try
        {
            await Service.DoWork();
        }
        catch (Exception ex)
        {
            logger.LogError($"Processing failed: {ex.Message}");
            throw;
        }
        
        logger.Log("Processing complete.");
    }
}

Logger Interface

The ITestLogger interface provides three levels of logging:

• Log(string message): General information.
• LogWarning(string message): Warnings that don't fail the test but should be noted.
• LogError(string message): Errors (often accompanied by a failure).

Default Behavior

By default, Prova uses a ConsoleLogger which writes appropriately colored output to the console.

CI/CD Integration

The ConsoleLogger automatically detects when it is running in GitHub Actions (GITHUB_ACTIONS=true) or Azure DevOps (TF_BUILD=True). When detected, it emits platform-specific service messages for warnings and errors (e.g., ::warning::, ::error::, ##vso[task.logissue]) so that they are properly annotated in the CI build summary.
