# Test With Log Stub
This is a class that stubs out `android.util.Log` for unit testing, using [PowerMock]() and [Mockito](). All `Log.*` methods are redirected to `System.out.println()`, so the output shows in the JUnit console. This allows easy unit testing of code with calls to `Log.*`, without requiring extensive modification to implement dependency injection, while still showing the output in the console.
## Usage
1. Copy `TestWithLogStub.java` to your project, and rename the package name to match your package.
2. Make sure you have the following lines in the `dependencies` block in your module-level `build.gradle`:
```java
testCompile 'junit:junit:4.12'
testCompile 'org.mockito:mockito-core:1.10.19'
testCompile 'org.powermock:powermock-api-mockito:1.6.6'
testCompile 'org.powermock:powermock-module-junit4:1.6.6'
```
3. Subclass the TestWithLogStub class, and add your own methods. Call `Log.*` as usual, and the output will be redirected to the console.
**Example:**
```java
package io.behindthemath.test;
import android.util.Log;
import org.junit.Test;
import static org.junit.Assert.assertEquals;
public class TestClass extends TestWithLogStub {
@Test
public void test() {
Log.i("TestClass", "This is a test");
assertEquals(true, true);
}
}
```
**Output:**
`I/TestClass: This is a test`
