Hamcrest Matchers Library

The Hamcrest Matchers Library provides additional Matcher implementations that work with Hamcrest for use in checking the results of operations being unit tested.

Pattern Matching

• matches - tests that the value matches a regular expression
• doesNotMatch - tests that a value does not match a regular expression

import static org.hamcrest.MatcherAssert.assertThat;
import static com.btmatthews.hamcrest.PatternMatcher.matches;

import org.junit.Test;

class TestPatternMatching {

  @Test
  public void idStringIsNumeric() {
    final Biscuit biscuit = new Biscuit("1234", "Custard Cream"));
    assertThat("id string is numeric", biscuit.getId(), matches("\\d+"));
  }
}
