方法详细资料

assertTrue

static void assertTrue(boolean value)

Assert if the given value is true.

参数:

value - the value to be asserted.

抛出:

IllegalStateException - if the given value is false.

assertTrue

static void assertTrue(boolean value,
                       Object message)

Assert if the given value is true.

参数:

value - the value to be asserted.

message - The exception message.

抛出:

IllegalStateException - with the given message if the given value is false.

assertTrue

static void assertTrue(boolean value,
                       String format,
                       Object... args)

Assert if the given value is true.

参数:

value - the value to be asserted.

format - exception message format.

args - exception message arguments.

抛出:

IllegalStateException - if the given value is false. The exception message is constructed by String.format(String, Object...) with the given format and arguments.

assertTrue

static void assertTrue(boolean value,
                       Supplier<Object> message)

Assert if the given value is true.

参数:

value - the value to be asserted.

message - The exception message supplier.

抛出:

IllegalStateException - with the given message if the given value is false.

assertSame

static void assertSame(long expected,
                       long computed,
