Question

How can I make google test fail if google mocked method is called more than expected times?

Here is the example:

class MockIO : iIO
{
    MOCK_METHOD1(IO_Read, void (uint8_t));
};

TEST(case, test)
{
    MockIO io;
    EXPECT_CALL(io, IO_Read(0x01)).Times(10);
    for (i=0; i<20; i++)
        io.IO_Read(0x01);
}

As I understand I should try

EXPECT_CALL(io, IO_Read(0x01)).Times(10).Throw(exception);

But in embedded projects exceptions not used.

Any ideas?

I think you should use strict mocks for your test.

TEST(case, test){
StrictMock<MockIO> io;
EXPECT_CALL(io, IO_Read(0x01)).Times(10);

When using a Strictmock, not expected calls cause a testfailure.
