鳳凰城測試數據持續存在，使測試不可重複

請注意，這是my forum post的副本。鳳凰城測試數據持續存在，使測試不可重複

我使用Phoenix（1.2.1）並在我的測試環境中遇到了問題。問題是跨越測試插入（更新，刪除等）的數據正在測試數據庫中持久存在，這使得我的測試不可重複。

首次運行：

[email protected]:/mnt/sidecar_api# mix test 
................................ 
Finished in 2.2 seconds 

32 tests, 0 failures 

Randomized with seed 180820

第二輪：

[email protected]:/mnt/sidecar_api# mix test 
........................... 

    1) test user signup with POST /v1/users with valid attributes (SidecarApi.V1.UserControllerTest) 
test/controllers/v1/user_controller_test.exs:15 
Assertion with == failed 
code: response == expected 
lhs: %{"jsonapi" => %{"version" => "1.0"}, "data" => %{"attributes" => %{"first-name" => "Juan", "last-name" => "Dela Cruz", "primary-email" => "[email protected]", "primary-mobile-number" => "639123456789", "username" => "jdelacruz"}, "type" => "user", "id" => "2"}} 
rhs: %{"jsonapi" => %{"version" => "1.0"}, "data" => %{"attributes" => %{"first-name" => "Juan", "last-name" => "Dela Cruz", "primary-email" => "[email protected]", "primary-mobile-number" => "639123456789", "username" => "jdelacruz"}, "type" => "user", "id" => "1"}} 
stacktrace: 
    test/controllers/v1/user_controller_test.exs:36: (test) 

.... 

Finished in 2.3 seconds 
32 tests, 1 failure 

Randomized with seed 556822

唯一的相關信息在這些情況下是對象ID。我正在檢查插入的記錄是否具有ID 1，這是我在執行所有測試之前對數據庫狀態的假設。

這裏是我的test.exs：

use Mix.Config 

config :sidecar_api, SidecarApi.Endpoint, 
    http: [port: 4001], 
    server: false 

config :logger, level: :warn 

config :sidecar_api, SidecarApi.Repo, 
    adapter: Ecto.Adapters.Postgres, 
    username: "sidecar", 
    password: "sidecardb", 
    database: "sidecar_test", 
    hostname: "sidecar-db-main", 
    pool: Ecto.Adapters.SQL.Sandbox

和test_helper.exs

ExUnit.start 

Ecto.Adapters.SQL.Sandbox.mode(SidecarApi.Repo, :manual)

注意，每個測試後，從psql檢查的Postgres的內容本身反映了空數據庫。用於開發和測試環境。現在，我很困惑在哪裏看。

sidecar_dev=# select * from users; 
id | username | password | first_name | last_name | inserted_at |  updated_at 
----+----------+----------+------------+-----------+-------------+------------ 
(0 rows) 


sidecar_test=# select * from users; 
id | username | password | first_name | last_name | inserted_at | updated_at 
----+----------+----------+------------+-----------+-------------+------------ 
(0 rows)

在此先感謝！

你確定這是不是因爲你的測試正在以不同的順序每次運行？ –

你可以附加更重要的片段 - 你的測試等。如果你運行測試的副作用功能，你記得不要異步使用它們嗎？ – PatNowak

看起來數據在運行之間被清除，但您的ID序列未被重置。

code: response == expected 
    lhs: %{"jsonapi" => %{"version" => "1.0"}, "data" => %{"attributes" => %{"first-name" => "Juan", "last-name" => "Dela Cruz", "primary-email" => "[email protected]", "primary-mobile-number" => "639123456789", "username" => "jdelacruz"}, "type" => "user", "id" => "2"}} 
    rhs: %{"jsonapi" => %{"version" => "1.0"}, "data" => %{"attributes" => %{"first-name" => "Juan", "last-name" => "Dela Cruz", "primary-email" => "[email protected]", "primary-mobile-number" => "639123456789", "username" => "jdelacruz"}, "type" => "user", "id" => "1"}}

注意，ID是不同
