Constructors

Assert()

We don't actually want any instances of this object, but some people like to inherit from it to add other static methods. Hence, the protected constructor disallows any instances of this object.

protected Assert()

Methods

AreEqual(double, double, double)

Verifies that two doubles are equal considering a delta. If the expected value is infinity then the delta value is ignored. If they are not equal then an AssertionException is thrown.

public static void AreEqual(double expected, double actual, double delta)

Parameters

expected double

The expected value

actual double

The actual value

delta double

The maximum acceptable difference between the the expected and the actual

AreEqual(double, double, double, string, params object[])
