assertEquals

public static void assertEquals(long expected,
                                long actual)

Asserts that two longs are equal. If they are not, an AssertionError is thrown.

 断言两个long类型是相等的。 如果它们不是，则抛出断言错误。 

Parameters:

expected - expected long value.

actual - actual long value

assertEquals

public static void assertEquals(String message,
                                long expected,
                                long actual)

Asserts that two longs are equal. If they are not, an AssertionError is thrown with the given message.

 断言两个long相等。 如果它们不是，则用给定的消息抛出断言错误。

Parameters:

message - the identifying message for the AssertionError (null okay)

expected - long expected value.

actual - long actual value

assertEquals

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

Asserts that two doubles are equal to within a positive delta. If they are not, an AssertionError is thrown. If the expected value is infinity then the delta value is ignored.NaNs are considered equal: assertEquals(Double.NaN, Double.NaN, *) passes

 断言两个double类型等于一个正增量内。 如果它们不是，则抛出断言错误。 如果期望值是无穷大，则忽略δ值。 NaNs被认为是相等的：assertEquals(Double.NaN, Double.NaN, *) passes

Parameters:

expected - expected value

actual - the value to check against expected

delta - the maximum delta between expected and actual for which both numbers are still considered equal.

assertEquals

public static void assertEquals(float expected, float actual, float delta)

断言两个float类型数等于一个正增量内。 如果它们不是，则抛出断言错误。 如果期望值是无穷大，则忽略δ值。 NaNs被认为是相等的： assertEquals(Float.NaN, Float.NaN, *) passes

Parameters:

expected - expected value

actual - the value to check against expected

delta - the maximum delta between expected and actual for which both numbers are still considered equal.
