代码示例

代码示例来源：origin: square/assertj-android

public MatrixAssert isIdentity() {
 isNotNull();
 assertThat(actual.isIdentity()) //
   .overridingErrorMessage("Expected to be identity matrix but was not.") //
   .isTrue();
 return this;
}

代码示例来源：origin: square/assertj-android

public MatrixAssert isNotIdentity() {
  isNotNull();
  assertThat(actual.isIdentity()) //
    .overridingErrorMessage("Expected to not be identity matrix but was.") //
    .isTrue();
  return this;
 }
}

@Test
public void testIsIdentity() {
 final Matrix matrix = new Matrix();
 assertThat(matrix.isIdentity())
   .isTrue();
 matrix.postScale(2.0f, 2.0f);
 assertThat(matrix.isIdentity())
   .isFalse();
}

@Test
public void testReset() {
 final Matrix matrix = new Matrix();
 matrix.postScale(2.0f, 2.0f);
 matrix.postTranslate(1.0f, 2.0f);
 matrix.postRotate(45.0f);
 matrix.reset();
 assertThat(matrix.isIdentity())
   .isTrue();
}

@Test
public void testSet() {
 final Matrix matrix1 = new Matrix();
 matrix1.postScale(2.0f, 2.0f);

 matrix1.postRotate(45.0f);
 final Matrix matrix2 = new Matrix();
 matrix2.set(matrix1);
 assertThat(matrix1)
   .isEqualTo(matrix2);
 matrix2.set(null);
 assertThat(matrix2.isIdentity())
   .isTrue();
}
