## Key Testing Patterns Used
|
||||
|
||||
### 1. Arrange-Act-Assert (AAA)
|
||||
Every test follows this pattern:
|
||||
```java
|
||||
@Test
|
||||
void should_DoSomething_When_Condition() {
|
||||
// Arrange - setup
|
||||
var input = new Input();
|
||||
|
||||
// Act - execute
|
||||
var result = sut.execute(input);
|
||||
|
||||
// Assert - verify
|
||||
assertThat(result).isEqualTo(expected);
|
||||
}
|
||||
```
|
||||
|
||||
### 2. Parameterized Tests
|
||||
For testing multiple similar inputs:
|
||||
```java
|
||||
@ParameterizedTest
|
||||
@ValueSource(strings = {"", " ", " "})
|
||||
void should_RejectBlankStrings(String input) {
|
||||
// Test runs 3 times with different inputs
|
||||
}
|
||||
```
|
||||
|
||||
### 3. Mocking Strategy
|
||||
- **Domain Layer**: No mocks (pure objects)
|
||||
- **Application Layer**: Mock external dependencies (Repository, Services)
|
||||
- **Infrastructure Layer**: Minimal mocks
|
||||
|
||||
```java
|
||||
@Mock
|
||||
private UserRepository userRepository;
|
||||
|
||||
@InjectMocks
|
||||
private CreateUser createUser; // Dependencies injected automatically
|
||||
```
|
||||
|
||||
### 4. AssertJ Fluent Assertions
|
||||
Clear, readable assertions:
|
||||
```java
|
||||
assertThat(user.username()).isEqualTo("john");
|
||||
assertThat(permissions).contains(Permission.USER_READ);
|
||||
assertThat(hash.value()).matches("\\$2[aby]\\$12\\$.*");
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Test Naming Convention
|
||||
|
||||
All tests follow: `should_ExpectedBehavior_When_StateUnderTest()`
|
||||
|
||||
Examples:
|
||||
- `should_CreateUser_When_ValidDataProvided()`
|
||||
- `should_FailWithInvalidCredentials_When_PasswordIncorrect()`
|
||||
- `should_ReturnUnmodifiableSet_When_PermissionsRetrieved()`
|
||||
- `should_ThrowException_When_NullPasswordHashProvided()`
|
||||
|
||||
This makes test intent immediately clear.
|
||||
|
||||

|
||||
|
||||
## Critical Business Logic Tests
|
||||
|
||||
### Authentication & Authorization
|
||||
1. **Locked user cannot login** - Status check happens before password verification
|
||||
2. **Inactive user cannot login** - UserInactive error returned
|
||||
3. **Permission aggregation** - User gets permissions from ALL assigned roles
|
||||
4. **Role assignment** - Users can have multiple roles
|
||||
|
||||
### Password Security
|
||||
1. **BCrypt strength 12** - Takes ~250ms to hash (resistant to brute force)
|
||||
2. **Password validation** - Requires: 8+ chars, upper, lower, digit, special
|
||||
3. **Unique salts** - Same password hashes differently each time
|
||||
4. **Constant-time verification** - Resistant to timing attacks
|
||||
|
||||
### Data Consistency
|
||||
1. **Bidirectional mapping** - Entity ↔ Domain preserves all data
|
||||
2. **Immutable collections** - Returned sets cannot be modified
|
||||
3. **Null safety** - Null inputs never cause crashes
|
||||
4. **Id-based equality** - Users/Roles equal by ID only
|
||||

|
||||
## How to Add More Tests
|
||||
|
||||
### Adding a new test to existing class:
|
||||
```java
|
||||
@Test
|
||||
@DisplayName("should_DoX_When_YCondition")
|
||||
void should_doX_when_yCondition() {
|
||||
// Arrange
|
||||
var input = setupTestData();
|
||||
|
||||
// Act
|
||||
var result = sut.execute(input);
|
||||
|
||||
// Assert
|
||||
assertThat(result).satisfies(r -> {
|
||||
// verify expectations
|
||||
});
|
||||
}
|
||||
```
|
||||
|
||||
### Adding a new test class:
|
||||
1. Create file in appropriate test directory
|
||||
2. Extend with `@DisplayName("Description")`
|
||||
3. Use `@ExtendWith(MockitoExtension.class)` if mocking
|
||||
4. Follow AAA pattern
|
||||
5. Use JUnit 5 annotations: `@Test`, `@BeforeEach`, `@ParameterizedTest`
|
||||

|
||||
|
||||
## Common Test Utilities
|
||||
|
||||
### AssertJ for Assertions
|
||||
```java
|
||||
// Strings
|
||||
assertThat(str).isNotBlank().hasSize(60);
|
||||
|
||||
// Collections
|
||||
assertThat(set).contains(item).hasSize(3);
|
||||
|
||||
// Exceptions
|
||||
assertThatThrownBy(() -> code())
|
||||
.isInstanceOf(IllegalArgumentException.class)
|
||||
.hasMessage("expected message");
|
||||
|
||||
// Numbers
|
||||
assertThat(value).isBetween(min, max);
|
||||
```
|
||||
|
||||
### Mockito for Mocking
|
||||
```java
|
||||
// Stubbing
|
||||
when(repo.findById(id)).thenReturn(Optional.of(user));
|
||||
|
||||
// Verification
|
||||
verify(repo).save(any());
|
||||
verify(logger).log(eq(EVENT), anyString(), any());
|
||||
|
||||
// Answer
|
||||
when(repo.save(any())).thenAnswer(invocation ->
|
||||
invocation.getArgument(0)
|
||||
);
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Debugging Failed Tests
|
||||
|
||||
### Show detailed assertion errors:
|
||||
```bash
|
||||
mvn clean test -Dorg.slf4j.simpleLogger.defaultLogLevel=debug
|
||||
```
|
||||
|
||||
### Run single test with stack trace:
|
||||
```bash
|
||||
mvn clean test -Dtest=com.effigenix.domain.usermanagement.UserTest#should_CreateUser_When_ValidDataProvided
|
||||
```
|
||||
|
||||
### Check test output:
|
||||
```bash
|
||||
cat target/surefire-reports/TEST-*.xml
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Test Maintenance Best Practices
|
||||
|
||||
1. **Keep tests independent** - No test should depend on another
|
||||
2. **Use meaningful names** - Name should explain what's being tested
|
||||
3. **One assertion per test** - Easier to debug failures
|
||||
4. **Mock external dependencies** - Keep tests fast
|
||||
5. **Test both paths** - Happy path AND error cases
|
||||
6. **Use setUp/BeforeEach** - Share common test data
|
||||
7. **Keep tests focused** - Test one thing per test class
|
||||
8. **Document complex tests** - Add comments for non-obvious logic
|
||||
|
||||

|
||||
|
||||
## Continuous Integration
|
||||
|
||||
These tests are designed to run in CI/CD pipelines:
|
||||
|
||||
```yaml
|
||||
# Example CI configuration
|
||||
test:
|
||||
script:
|
||||
- mvn clean test
|
||||
coverage: '/[0-9]+%/'
|
||||
artifacts:
|
||||
reports:
|
||||
junit: target/surefire-reports/*.xml
|
||||
```
