--- name: bunit-test-migration description: Migrate bUnit test files from deprecated beta API (1.0.0-beta-10) to bUnit 2.x stable API. Use this when working on .razor test files in BlazorWebFormsComponents.Test that contain old patterns like TestComponentBase, Fixture, or SnapshotTest. --- # bUnit Test Migration Skill (Beta → 2.x) This skill provides guidance for migrating test files from the deprecated bUnit 1.0.0-beta-10 API to bUnit 2.5.3 stable API. Use this when you encounter test files using the old `TestComponentBase`, ``, or `` patterns. ## When to Apply Apply this skill when a `.razor` test file contains any of these patterns: - `@inherits TestComponentBase` - `` - `` - `` - `void MethodName(Fixture fixture)` ## Transformation Rules ### 1. Change Inheritance ```diff - @inherits TestComponentBase + @inherits BunitContext ``` ### 2. Remove Wrapper Elements Remove these XML elements entirely (keep only the component inside): ```diff - - - <\/ComponentUnderTest> - <\/Fixture> ``` ### 3. Convert Test Methods ```diff - void TestMethodName(Fixture fixture) + [Fact] + public void ComponentName_Scenario_ExpectedResult() ``` ### 4. Replace Component Access ```diff - var cut = fixture.GetComponentUnderTest(); + var cut = Render(@); ``` ### 5. Convert Snapshot Tests ```diff - - - - <\/TestInput> - -

expected html<\/div> - <\/ExpectedOutput> - <\/SnapshotTest> + [Fact] + public void MyComponent_Default_RendersCorrectly() + { + var cut = Render(@); + cut.MarkupMatches(@

expected html<\/div>); + } ``` ## Complete Example ### Before ```razor @inherits TestComponentBase
