英文:

Unable to run JUnit test of JPA Repository with H2 database - why is no data returned?

问题

更新： 不知何故数据未被插入。已执行删除表和创建表操作，但未插入行。我将data.sql移动到src/test/resources/目录下。

我正在测试使用H2数据库的SpringBoot应用程序。它正在IntelliJ IDE中运行。

当我在IDE中启动SpringBoot应用程序时，我可以在浏览器中查询控制台http://localhost:8080/h2-console。但是，当我停止IDE时，无法访问。application.properties中的数据库URL为spring.datasource.url=jdbc:h2:~/test。

我的其他JUnit测试正常运行（使用模拟存储库）。

当我测试存储库时，我运行SpringBoot应用程序以确保数据库存在，但我收到一个长度为零的列表。

@ExtendWith(SpringExtension.class)
@DataJpaTest
class EncouragementRepositoryTest {
    @Autowired
    EncouragementRepository repository;

    @BeforeEach
    void setUp() {
    }

    @Test
    public void find_all() {
        List<Encouragement> list = repository.findAll();
        assertEquals(33, list.size());
    }
}

我不知道为什么它失败并返回长度为零的列表。

因此，我认为可能是数据库没有被填充。

我将数据库URL更改为：

spring.datasource.url=jdbc:h2:~/test;INIT=RUNSCRIPT FROM '~/Documents/Projects/regular-encourager/encourage/src/main/resources/data.sql';

在src/main/resources/data.sql中，我包含了以下脚本：

drop table ENCOURAGEMENT if exists;
CREATE TYPE Category AS ENUM('WhoIAmInChrist','Default');
CREATE TYPE Tone AS ENUM('Default', 'Uplifting', 'Urging', 'Warning', 'Soothing', 'Comforting', 'Inspiring', 'Centering', 'Balanced');
CREATE TYPE Topic AS ENUM('Default', 'AcceptedInChrist', 'SignificantInChrist', 'SecureInChrist', 'NoAnxietyInChrist');
CREATE TABLE Encouragement(ID INT PRIMARY KEY, CATEGORY Category, TOPIC Topic, TONE Tone, MESSAGE VARCHAR(512));
INSERT INTO Encouragement VALUES(-1, 'Default', 'Default', 'Default', 'We walk by Faith, not by Sight');
INSERT INTO Encouragement VALUES(0,'WhoIAmInChrist','AcceptedInChrist','Uplifting','John 1:12 I am God\'s child.');
INSERT INTO Encouragement VALUES(1,'WhoIAmInChrist','AcceptedInChrist','Uplifting','John 15:15 As a disciple, I am a friend of Jesus Christ.');
...

这是IDE控制台的输出。

我查看了类似https://stackoverflow.com/q/38022284/398348的SO问题，但它不适用，因为我没有使用事务。

更新：

我尝试在data.sql中添加以下内容：

drop TYPE Category if exists;
drop TYPE Tone if exists;
drop TYPE Topic if exists;

但没有变化。

英文:

Update: somehow the data is not being inserted. the drop table and create table is executed but not the insert rows. I moved data.sql to src/test/resources/

I am testing my SpringBoot application which uses the H2 db.
It is running in IntelliJ IDE.

When I launch the SpringBoot application in the IDE, I can query the console http://localhost:8080/h2-console in the browser. When I stop the IDE, I am unable to.
The DB url in application.properties is spring.datasource.url=jdbc:h2:~/test.

My other JUnit tests are working (mocked repository).

When I test the repository,
I run the SpringBoot application so that the DB is present,
but I get a zero length list back.

@ExtendWith(SpringExtension.class)
@DataJpaTest
class EncouragementRepositoryTest {
@Autowired
EncouragementRepository repository;
    @BeforeEach
    void setUp() {
    }
    @Test
    public void find_all() {
        List&lt;Encouragement&gt; list = repository.findAll();
        assertEquals(33,list.size());
    }
}

I don't know why it is failing and returning zero length list.

So I thought perhaps the DB isn't seeded.

I changed the db url to

spring.datasource.url=jdbc:h2:~/test;INIT=RUNSCRIPT FROM '~/Documents/Projects/regular-encourager/encourage/src/main/resources/data.sql'

In src/main/resources/data.sql I included a script like this:

drop table ENCOURAGEMENT if exists;
CREATE TYPE Category AS ENUM(&#39;WhoIAmInChrist&#39;,&#39;Default&#39;);
CREATE TYPE Tone AS ENUM(&#39;Default&#39;, &#39;Uplifting&#39;, &#39;Urging&#39;, &#39;Warning&#39;, &#39;Soothing&#39;, &#39;Comforting&#39;, &#39;Inspiring&#39;, &#39;Centering&#39;, &#39;Balanced&#39;);
CREATE TYPE Topic AS ENUM(&#39;Default&#39;, &#39;AcceptedInChrist&#39;, &#39;SignificantInChrist&#39;, &#39;SecureInChrist&#39;, &#39;NoAnxietyInChrist&#39;);
CREATE TABLE Encouragement(ID INT PRIMARY KEY, CATEGORY Category, TOPIC Topic, TONE Tone, MESSAGE VARCHAR(512));
INSERT INTO Encouragement VALUES(-1, &#39;Default&#39;, &#39;Default&#39;, &#39;Default&#39;, &#39;We walk by Faith, not by Sight&#39;);
INSERT INTO Encouragement VALUES(0,&#39;WhoIAmInChrist&#39;,&#39;AcceptedInChrist&#39;,&#39;Uplifting&#39;,&#39;John 1:12 I am God&#39;&#39;s child.&#39;);
INSERT INTO Encouragement VALUES(1,&#39;WhoIAmInChrist&#39;,&#39;AcceptedInChrist&#39;,&#39;Uplifting&#39;,&#39;John 15:15 As a disciple, I am a friend of Jesus Christ.&#39;);

.....

Here is the IDE console:

I looked at SO questions like https://stackoverflow.com/q/38022284/398348 but it did not apply as I am not using a transaction.

Update:

I tried adding to data.sql

drop TYPE Category if exists;
drop TYPE Tone if exists;
drop TYPE Topic if exists;

But no change
