參數比對

利用 Call::With() 比對參數

#include "hippomocks.h"

bool isOdd(int i) {
    return 0 != i % 2;
}

TEST(Demo, With) {

    MockRepository mocks;

    EXPECT_TRUE(isOdd(1));                              // pass
    EXPECT_FALSE(isOdd(2));                             // pass

    mocks.ExpectCallFunc(isOdd).With(1).Return(false);
    mocks.ExpectCallFunc(isOdd).With(2).Return(true);

    EXPECT_FALSE(isOdd(1));                             // pass
    EXPECT_TRUE(isOdd(2));                              // pass
}

也支援多個參數

#include "hippomocks.h"

bool isSame(int a, int b) {
    return a == b;
}

TEST(Demo, With) {

    MockRepository mocks;

    EXPECT_TRUE(isSame(1, 1));                                 // pass
    EXPECT_FALSE(isSame(1, 2));                                // pass

    mocks.ExpectCallFunc(isSame).With(1, 1).Return(false);
    mocks.ExpectCallFunc(isSame).With(1, 2).Return(true);

    EXPECT_FALSE(isSame(1, 1));                                // pass
    EXPECT_TRUE(isSame(1, 2));                                 // pass
}

透過 Call::Match 傳入自訂的方法比對參數

#include "hippomocks.h"

bool isOdd(int i) {
    return 0 != i % 2;
}

TEST(Demo, Match) {

    MockRepository mocks;

    EXPECT_TRUE(isOdd(1));                                    // pass
    EXPECT_FALSE(isOdd(2));                                   // pass

    auto m1 = [](int i){ return i == 1; };
    auto m2 = [](int i){ return i == 2; };

    mocks.ExpectCallFunc(isOdd).Match(m1).Return(false);
    mocks.ExpectCallFunc(isOdd).Match(m2).Return(true);

    EXPECT_FALSE(isOdd(1));                                   // pass
    EXPECT_TRUE(isOdd(2));                                    // pass
}
