FEST Assertions Module has moved to Github !
Check this page :https://github.com/alexruiz/fest-assert-2.x/wiki
The documentation below is for Fest 1.x which is no more maintained, we are focusing our effort to the 2.x version !
....
Here's a list of find/replace based on regexp that allow to change JUnit assertion into FEST assertion (don't forget to check regexp mode in your editor replace window).
A similar idea would be to use the Structured Search and Replace (SSR) feature of IntelliJ IDEA.
Note that FEST & JUnit assertions can coexist together, you don't have to migrate all in one time.
Changing
assertEquals(0, myList.size())to
assertThat(myList).isEmpty()It's important to run this one before the assertEquals -> isEqualTo, to avoid ending with : assertThat(myList.size()).isEqualTo(0)
Changing
assertEquals(expectedSize, myList.size())to
assertThat(myList).hasSize(expectedSize)It's important to run this one before the assertEquals -> isEqualTo, to avoid ending with : assertThat(myList.size()).isEqualTo(expectedSize)
Changing
assertEquals(value, valueUnderTest)to
assertThat(valueUnderTest).isEqualTo(value)Changing
assertNotEquals(value, valueUnderTest)to
assertThat(valueUnderTest).isNotEqualTo(value)Changing
assertNull(objectUnderTest)to
assertThat(objectUnderTest).isNull()Changing
assertNotNull(objectUnderTest)to
assertThat(objectUnderTest).isNotNull()Changing
assertTrue(logicalCondition)to
assertThat(logicalCondition).isTrue()Changing
assertFalse(logicalCondition)to
assertThat(logicalCondition).isFalse()
