使用 Mox 测试函数链中的多个 API 调用
Testing multiple API calls in a function chain with Mox
我正在尝试测试我是否正在正确转换从第三方 api 返回的数据。我在使用 Mox 时遇到了一些麻烦,因为我需要在数据转换期间访问两个不同的端点。让我通过发布代码更清楚地解释:
测试:
test "players/0 return all active players" do
Statcasters.SportRadarNbaApi.ClientMock
|> expect(:league_hierarchy, fn ->
{:ok, league_hierarchy_map()}
end)
Statcasters.SportRadarNbaApi.ClientMock
|> expect(:team_profile, fn _ ->
{:ok, team_profile_map()}
end)
assert Statcasters.Sports.Nba.get_players() == ["Kevon Looney", "Patrick McCaw"]
end
代码:
def get_players do
with {:ok, hierarchy} <- @sport_radar_nba_api.league_hierarchy,
team_ids <- get_team_ids(hierarchy),
players <- get_team_players(team_ids)
do
IO.inspect players
end
end
defp get_team_players(team_ids) do
for team_id <- team_ids do
{:ok, team} = @sport_radar_nba_api.team_profile(team_id)
end
end
忽略编写的代码实际上不会通过测试的事实。这是我试图弄清楚的测试失败。
问题:
第二个 api 调用 team_profile
在测试中被调用了两次,因为我遍历了两个 team_ids
并且对于每个 team_id
我调用了 API .这是预期的,但测试没有为此做好准备,因为我收到此错误。
错误:
** (Mox.UnexpectedCallError) expected Statcasters.SportRadarNbaApi.ClientMock.team_profile/1 to be called once but it has been called 2 times in process #PID<0.410.0>
这是正确的。我确实调用了两次,但是如何设置测试以预期此 API 端点将被调用两次?
third optional argument to expect
是模拟函数应该被调用的次数。在这种情况下,只需将其设置为 2
:
Statcasters.SportRadarNbaApi.ClientMock
|> expect(:team_profile, 2, fn _ ->
{:ok, team_profile_map()}
end)
