name: test-architect description: Write high-coverage tests (TDD preferred)

test-architect

TDD workflow:

1. Write failing test first
2. Implement minimum code to pass
3. Refactor

Target: 80%+ coverage on changed code

Framework Commands

.NET/Blazor Testing Patterns

Unit test (xUnit):

Copy[Fact]
public void Player_MovesWithinBounds()
{
    var player = new Player { X = 100 };
    player.MoveLeft(10);
    Assert.Equal(90, player.X);
}

Blazor component test (bUnit):

Copy[Fact]
public void ScoreDisplay_ShowsCurrentScore()
{
    using var ctx = new TestContext();
    var cut = ctx.RenderComponent<ScoreDisplay>(p => p.Add(x => x.Score, 500));
    cut.Find(".score").TextContent.Should().Contain("500");
}

Integration with back-pressure

Tests must pass before any commit. If tests fail repeatedly, invoke circuit-breaker skill.
