我试图测试我是否正在正确地转换从第三方api返回的数据。我在使用Mox时遇到了一些问题,因为在数据转换期间,我需要访问两个独立的端点。让我通过发布代码更清楚地解释一下:
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
忽略这样一个事实:编写的代码实际上不会通过测试。我想弄清楚的是测试失败。
问题:
第二个api调用
team_profile
在测试中被调用两次,因为我遍历了两个
team_ids
为每个人
team_id
我调用API。这是预料中的,但测试没有准备好,因为我得到了这个错误。
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期望此API端点将被调用两次?
