java.time Assertions

The following documentation is a overview around the assertions for java.time.LocalDateTime, java.time.LocalDate and java.time.LocalTime

Not all cases are covered, but all methods work as appropriate to the tested datetype. All examples can be found in the testsuites .

There are extension functions for x.years(), x.months(), x.days(), x.hours(), x.minutes() and x.seconds().

// Test that a LocalDateTime is after another
val dateToTest = LocalDateTime.of(2017, 3, 1, 10, 0)
val dateBefore = dateToTest.minusDays(1)

// Test that a LocalDateTime is before another
val dateToTest = LocalDateTime.of(2017, 3, 1, 10, 0)
val dateAfter = dateToTest.plusDays(1)
dateToTest shouldBeBefore dateAfter

// Test that a LocalDateTime is on or after another

// Test that a LocalDateTime is on or before another
val dateToTest = LocalDateTime.of(2017, 3, 1, 10, 0)
