# org.junit.jupiter.api.extension.ParameterResolutionException: No ParameterResolver registered for parameter [int arg0] in constructor

- **ID:** `java/junit-parameterized-test-no-source`
- **Domain:** java
- **Category:** config_error
- **Verification:** ai_generated
- **Fix Rate:** 80%

## Root Cause

Parameterized test method or constructor has parameters but no @ValueSource or other source annotation.

## Version Compatibility

| Version | Status | Introduced | Deprecated |
|---------|--------|------------|------------|
| 8+ | active | — | — |

## Workarounds

1. **Add @ValueSource with values** (95% success)
   ```
   @ParameterizedTest
@ValueSource(ints = {1, 2, 3})
void testWithInts(int num) {
    assertTrue(num > 0);
}
   ```
2. **Use @CsvSource for multiple parameters** (90% success)
   ```
   @ParameterizedTest
@CsvSource({"1, foo", "2, bar"})
void testWithCsv(int id, String name) {
    assertNotNull(name);
}
   ```

## Dead Ends

- **Adding @ParameterizedTest without source** — JUnit doesn't know where to get parameters from. (80% fail)
- **Using @Test instead of @ParameterizedTest** — Test won't be parameterized and will fail with missing arguments. (60% fail)
