# Testing
### 7 Testing Principles
| Principle | Description |
|-----------------------------------|----------------------------------------------------------------------------------------|
| Testing is context dependent | |
| Exhaustive testing is impossible | Perfect testing does not exist |
| Defect clustering | |
| Early testing is always preferred | Test as early as possible |
| Pesticide paradox | When we repeat the same tests, they become ineffective over time |
| Testing shows presence of defects | - Testing can show us that there are problems
- CANNOT say that there are no bugs |
| Absence-of-errors fallacy | |
### Unit testing
- Each test is `public void`
- `@Before`
- Gets executed before each test
- Prepares data for the test
### 3 A Pattern
`Arrange` - Preconditions - The data should correspond to the situation we want to recreate.
`Act` - Test a single behavior.
`Assert` - Post conditions - Expected behavior.
```
@Test
public void depositShouldAddMoney() {
BankAccount account = new BankAccount(); // Arrange
account.deposit(50); // Act
Assert.assertTrue(account.getBalance() == 50); // Assert
}
```
Exception testing
```
@Test(expected - IllegalArgumentException.class) // Assert
public void depositNegativeShouldNotaddMoney() {
BankAccount account = new BankAccount(); // Arrange
account.deposit(-50); // Act
}
```
