Question

Math expression unit test

Answer 1

To create a unit test for a math expression, you can use a testing framework like JUnit in Java. Here is an example unit test for a simple math expression:

```java
import static org.junit.Assert.assertEquals;
import org.junit.Test;

public class MathExpressionTest {

@Test
public void testSimpleExpression() {
int result = 2 + 3 * 4;
assertEquals(14, result);
}

@Test
public void testComplexExpression() {
int result = (2 + 3) * 4 / 2;
assertEquals(10, result);
}
}
```

In this unit test, we have two test methods that evaluate the result of different math expressions. The `assertEquals` method is used to verify that the actual result matches the expected result. You can add more test methods to cover different scenarios and edge cases of your math expressions.
