使用 Google 测试测试 Map<int, vector>

Question

这些在我的 class 的 Game 头文件中：订单是另一个 class.

std::map<int, std::vector<Order>> ordersToBeExecuted;

std::map<int, std::vector<Order>> getOrdersToBeExecuted();

这是我的 cpp 文件中的定义：

std::map<int, std::vector<Order>> Game::getOrdersToBeExecuted()
{
    return this->ordersToBeExecuted;
}

现在，我不知道如何测试它。我正在尝试 Google 测试。我正在写这篇文章，但目前，我收到一个错误：

#define EXPECT_EQ(val1,val2) EXPECT_PRED_FORMAT2(::testing::internal:: EqHelper<GTEST_IS_NULL_LITERAL_(val1)>::Compare, val1, val2)
Expands to:

EXPECT_PRED_FORMAT2(::testing::internal:: EqHelper<GTEST_IS_NULL_LITERAL_(std::map<0)>::Compare, std::map<0, std::vector<<Order>>)
expected a type specifier


TEST(gameTest, getOrdersToBeExecutedTest) {

    std::map<int, std::vector<Order>> first;
    std::vector<Order> orders;
    Game g;
    Order o1;
    Order o2;
    orders.push_back(o1);
    orders.push_back(o2);
    first[0] = orders;
    g.setNumberOfPlayers(1);

    EXPECT_EQ(std::map<0,std::vector<Order>>, g.getOrdersToBeExecuted());
}

编辑：

TEST(gameTest, getOrdersToBeExecutedTest) {

    std::map<int, std::vector<Order>> first;
    std::vector<Order> orders;
    std::vector<Order> orders2;
    Game g;
    Order o1, o2;
    Order o3, o4;
    orders.push_back(o1);
    orders.push_back(o2);
    orders2.push_back(o3);
    orders2.push_back(o4);
    first[0] = orders;
    first[1] = orders2;
    //EXPECT_EQ(first, g.getOrdersToBeExecuted());


EXPECT_THAT(g.getOrdersToBeExecuted()), ElementsAre(Pair(0, ElementsAre(o1, o2)), Pair(1, ElementsAre(o3, o4)));
}

我正在尝试使用，但我仍然遇到这些错误：

#define EXPECT_THAT(value,matcher) EXPECT_PRED_FORMAT1( ::testing::internal::MakePredicateFormatterFromMatcher(matcher), value)
Expands to:

EXPECT_PRED_FORMAT1( ::testing::internal::MakePredicateFormatterFromMatcher(), g.getOrdersToBeExecuted())
identifier "EXPECT_THAT" is undefined

要使用容器匹配器测试容器，请参阅：https://github.com/google/googletest/blob/master/googlemock/docs/cheat_sheet.md

Map有点棘手，因为它是pairs的容器，所以你必须将它与Pair匹配器结合起来，例如：

using testing::ElementsAre;
using testing::Pair;

EXPECT_THAT(g.getOrdersToBeExecuted()), ElementsAre(Pair(key1, val1), Pair(key1, val2)));

当值类型为vector时，需要在里面放入容器匹配器：

using testing::ElementsAre;
using testing::Pair;

EXPECT_THAT(g.getOrdersToBeExecuted()), ElementsAre(Pair(key1, ElementsAre(e1, e2, e3)), Pair(key1, ElementsAre(e4, e5)));
