mvn clean test
|
||||
```
|
||||
|
||||
### Run by layer:
|

## Key Testing Patterns
|
||||
|
||||
### 1. Arrange-Act-Assert
|
||||
```java
|
||||
@Test
|
||||
void should_DoX_When_Condition() {
|
||||
// Arrange
|
||||
var input = new Input();
|
||||
|
||||
// Act
|
||||
var result = sut.execute(input);
|
||||
|
||||
// Assert
|
||||
assertThat(result).isEqualTo(expected);
|
||||
}
|
||||
```
|
||||
|
||||
### 2. Parameterized Tests
|
||||
```java
|
||||
@ParameterizedTest
|
||||
@ValueSource(strings = {"", " ", " "})
|
||||
void should_RejectBlanks(String input) {
|
||||
// Test runs with each value
|
||||
}
|
||||
```
|
||||
|
||||
### 3. Mocking
|
||||
```java
|
||||
@Mock
|
||||
private UserRepository repo;
|
||||
|
||||
@InjectMocks
|
||||
private CreateUser createUser;
|
||||
|
||||
// In test:
|
||||
when(repo.save(any())).thenReturn(user);
|
||||
verify(repo).save(any());
|
||||
```
|
||||
|
||||
### 4. AssertJ Fluent Assertions
|
||||
```java
|
||||
assertThat(user.username()).isEqualTo("john");
|
||||
assertThat(permissions).contains(Permission.USER_READ);
|
||||
assertThat(hash.value()).matches("\\$2[aby]\\$12\\$.*");
|
||||
assertThatThrownBy(() -> new UserId(null))
|
||||
.isInstanceOf(IllegalArgumentException.class);
|
||||
```
|
||||
|
||||
## Critical Business Logic Covered
|
||||
|
||||
### Authentication & Authorization
|
||||
- ✅ Locked users cannot login
|
||||
- ✅ Inactive users cannot login
|
||||
- ✅ Invalid passwords rejected
|
||||
- ✅ Permissions aggregated from all roles
|
||||
- ✅ Audit trail recorded
|
||||
|
||||
### Password Security
|
||||
- ✅ BCrypt strength 12 (4096 iterations)
|
||||
- ✅ Password validation rules enforced
|
||||
- ✅ Unique salts (same password hashes differently)
|
||||
- ✅ Constant-time verification (timing attack resistant)
|
||||
- ✅ No plain-text passwords stored
|
||||
|
||||
### Data Consistency
|
||||
- ✅ Bidirectional mapping preserves all data
|
||||
- ✅ Immutable collections returned to users
|
||||
- ✅ Null safety throughout
|
||||
- ✅ ID-based equality for entities
|
||||
- ✅ Set independence (no shared references)
|
||||
|
||||
## Dependencies & Libraries
|
||||
|
||||
```xml
|
||||
<!-- JUnit 5 (included with spring-boot-starter-test) -->
|
||||
<dependency>
|
||||
<groupId>org.springframework.boot</groupId>
|
||||
<artifactId>spring-boot-starter-test</artifactId>
|
||||
<scope>test</scope>
|
||||
</dependency>
|
||||
```
|
||||
|
||||
Provides:
|
||||
- JUnit 5 (Jupiter)
|
||||
- Mockito
|
||||
- AssertJ
|
||||
- Spring Test
|
||||
|
||||
## Test Naming Convention
|
||||
|
||||
All tests follow: `should_ExpectedBehavior_When_StateUnderTest()`
|
||||
|
||||
Examples:
|
||||
- `should_CreateUser_When_ValidDataProvided()`
|
||||
- `should_FailWithInvalidCredentials_When_PasswordIncorrect()`
|
||||
- `should_ThrowException_When_NullPasswordHashProvided()`
|
||||
- `should_ReturnUnmodifiableSet_When_PermissionsRetrieved()`
|
||||
|
||||
This makes intent immediately clear.
|
||||
|
||||
## Maintenance & Future Work
|
||||
|
||||
### To add more tests:
|
||||
1. Add `@Test` method to existing test class
|
||||
2. Follow AAA pattern (Arrange-Act-Assert)
|
||||
3. Use existing test naming convention
|
||||
4. Update test documentation
|
||||
|
||||
### To improve coverage:
|
||||
1. Run: `mvn clean test jacoco:report`
|
||||
2. Check: `target/site/jacoco/index.html`
|
||||
3. Find uncovered branches
|
||||
4. Add test cases to cover gaps
|
||||
|
||||
### Common additions:
|
||||
- Edge case handling
|
||||
- Boundary conditions
|
||||
- Exception paths
|
||||
- Integration scenarios
|
||||
- Performance tests
|
||||
|
||||
