Spock - approximate comparisions

I’ve been looking for the Spock equivalent of the following convenience method in JUnit whereby you can do “approximate” comparisons. Does anyone know if such a thing exists?

/**
 * Asserts that two doubles or floats are equal to within a positive delta.
 */
assertEquals(double expected, double actual, double delta)
Solution

  • There is build in function for that, described in official docs:

    when:
def x = computeValue()

then:
expect x, closeTo(42, 0.01)

    Check the specs.
