| description | [Library contributor] Adds tests for the ktnip KSP processor. Use when adding tests for a new collector, testing processor behavior with new annotations, or verifying KSP code generation for the telegram-bot library. |
Add Ktnip KSP Tests
Workflow
1. Test Data
- Create Kotlin source in
ktnip/src/jvmTest/resources/test-data/
- Name:
FeatureName.kt (e.g. NewHandler.kt)
- Must import from telegram-bot (project dependency)
- Include valid handlers with annotations being tested
2. Add to ProcessorTest
- In ProcessorTest.kt
- Add
@Test fun featureName() = runTest("test-data/FeatureName.kt")
3. Custom Assertions (optional)
- Use
compile(vararg SourceFile, ...) instead of runTest for custom checks
- Returns
JvmCompilationResult; inspect exitCode, kspSourcesDir, generated files
- Pass custom
symbolProcessors or processorProviders
runTest Behavior
- Loads source from resources
- Compiles with ActivityProcessorProvider (default)
- Asserts
exitCode == OK (or COMPILATION_ERROR when error directives present)
- Verifies generated files exist (ActivitiesData.kt, KtGramCtxLoader.kt, BotCtx.kt)
- Parses
/* G-EXPECT ... */ blocks for golden output checks
Golden Output
Two modes (hybrid):
- Golden files (preferred): If
test-data/golden/<TestName>/<FileName>.gold exists, full file content is compared.
- G-EXPECT (fallback): When no golden exists, use inline
/* G-EXPECT ... */ block in test data.
G-EXPECT is optional when golden files exist โ expectations are discovered from golden files automatically.
Update golden files: ./gradlew :ktnip:updateGolden โ run when generated output changes intentionally.
G-EXPECT (fallback)
Add /* G-EXPECT ... */ block to test data when no golden file exists:
Directives: file=, contains="...", notContains="...", matches="regex", notMatches="regex", noError, error contains=, error exact=, error count=, error file=X line=Y contains=
