Parameters

• notExpected
  Type: Double

  The first double to compare. This is the double the unit test expects not to match actual.

• actual

  The second double to compare. This is the double the unit test produced.

• delta

  The required inaccuracy. The assertion will fail only if notExpected is equal to actual or different from it by less than delta.

• message
  Type: String

  A message to display if the assertion fails. This message can be seen in the unit test results.

• parameters
  Type: array<Object[]

  An array of parameters to use when formatting message.
