Dubbo Frame Write Junit Error: ERROR org.springframework.test.context.Testcontextmanager

Solution:

Since the Dubbo framework is used, on the premise that we confirm that there is no problem with JUnit unit test environment:

First, check whether the Dubbo service is enabled; Secondly, if the test class is written in the consumer module, you need to check whether the provider service is enabled;

Start the corresponding service to solve the problem.

Detailed error reporting information is as follows:

[main] ERROR org. springframework. test. context. TestContextManager – Caught exception while allowing TestExecutionListener [org.springframework.test.context.support. DependencyInjectionTestExecutionListener@333398f ] to prepare test instance [com.yangdaxian.test. MyTest@103c97ff ]

Some detailed error messages are as follows:

error code

import org.junit.Test;

public class Test01 {

    @Test
    public void test(){
        System.out.println("hello world");
    }
}

reason

There is no problem with the code @ test annotation is placed on the method, and the @test annotation is also from the package org.junit.Test

Simulate the environment where the problem code occurs: Maven project, with a main/Java/test01.Java and test/Java/test01.Java class

main/java/Test01.java

import org.junit.Test;

public class Test01 {
    @Test
    public void test01() {
        System.out.println("hello world - main/java/Test01.java");
    }
}

test/java/Test01.java

public class Test01 {
    public static void main(String[] args) {
        System.out.println("hello world - test/java/Test01.java");
    }
}

To solve the above problems, the following conditions must be met:

1.The same path. It means that the path of the class must be at the same level. If the test/java/Test01.javaand mian/java/Test01.javais the same level, the test/java/Test01.javaand mian/java/hello/Test01.javais not the same level , and there will be no conflict.
2.Same class name. Refer to the same class name in the same path as test/java/Test01.javathe main/java/Test01.javasame path and is both the name of the same class, test/java/Test02.javawith the main/java/Test01.javaconflict although the same path but different class name, it will not happen.
3.Use @Testcomments or not. In the case where the path and class name are the same, if main/java/Test01.javathere is an @Testannotated method in it, and test/java/Test01.javathere must be no @Testannotated method in it, this conflict will occur. If there is an @Testannotated method and the method name is different, it will be reported to use Junit Unit test error “No tests found matching Method test01(Test01) from ClassRequest@5387f9e0” .

After the above conditions are met, the above error will be reported by executing the test method with @test annotation under main/Java .

Solution:

Make their class paths different.

Make their class names different

Under test/Java, there must be methods using @test annotations

In short, it is recommended not to write test methods with @test comments under main/Java, let alone conflict them.

        <property name="dataSource" value="dataSource"></property>
        <property name="typeAliasesPackage" value="com.itheima.domain"></property>
    </bean>

Reason: because we use the factory to create Dao objects, we need to get connections from the data connection pool objects, so we can’t use value binding
value for binding strings
ref for binding objects

The correct is as follows: use ref to get the object

<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
        <property name="dataSource" ref="dataSource"></property>
        <property name="typeAliasesPackage" value="com.itheima.domain"></property>

    }




public static CuratorFramework getCuratorFramework() {

Error reporting reason

Websocket needs to be started by relying on containers such as Tomcat

Solution:

Add “webenvironment = springboottest. Webenvironment. Random_port” after springboottest, which means to create a web application context.

For a complete example, refer to the following code:

package org.jeecg;

import lombok.extern.slf4j.Slf4j;
import org.jeecg.modules.info.cache.DataCache;
import org.jeecg.modules.info.service.IWrSeasonBService;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.junit4.SpringRunner;


@RunWith(SpringRunner.class)
@SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT)
@Slf4j
public class DataCacheTest {

    @Autowired
    DataCache dataCahche;

    @Autowired
    IWrSeasonBService iWrSeasonBService;


    @Test
    public void irrSeasonTest() {
        log.info("========================");
        log.info("irrigation season cache test");
        log.info("irrigation season name:" + "spring irrigation");
        String str = dataCahche.getStartEndDateBySeasonNm("spring irrigation");
        // assertEquals("2021-03-01,2021-04-30", str);
        String[] arr = str.split(",");
        if (arr != null && !arr.equals("null")) {
            log.info("Start date, end date:" + arr[0] + "," + arr[1]);
        } else {
            log.info("Record cache does not exist");
        }
        log.info("========================");

Junit4 unit test reports an error invalid project specified

Junit4 unit test reports an error invalid project specified.

During the unit test the day before yesterday, an invalid project specified error was reported. After checking, it was found that the problem was the project name. If there are illegal characters such as’ – ‘or space in the project name, an error invalid project specified will be reported when running

[Solved] Vue unit test syntax error: unexpected token ‘export‘

Paste error information to facilitate search engines to find similar errors

Jest encountered an unexpected token

    This usually means that you are trying to import a file which Jest cannot parse, e.g. it's not plain JavaScript.

    By default, if Jest sees a Babel config, it will use that to transform your files, ignoring "node_modules".

    Here's what you can do:
     • To have some of your "node_modules" files transformed, you can specify a custom "transformIgnorePatterns" in your config.
     • If you need a custom transformation specify a "transform" option in your config.
     • If you simply want to mock your non-JS modules (e.g. binary assets) you can stub them out with the "moduleNameMapper" config option.

    You'll find more details and examples of these config options in the docs:
    https://jestjs.io/docs/en/configuration.html

    Details:

    D:\123\vue3-pro\h5-editor\node_modules\[email protected]@lodash-es\lodash.js:10
    export { default as add } from './add.js';
    ^^^^^^

    SyntaxError: Unexpected token 'export'

Solution

After checking online for a long time, I finally found the only way to solve my problem. If the common methods on the Internet are useless, friends can try

According to the reply to the question, you can configure the following in jest. Config. JS 

"transformIgnorePatterns": [
  "<rootDir>/node_modules/(?!lodash-es)"
]

[Solved] Android Could not determine artifacts for XXXX: Skipped due to earlier error

Recently, I encountered the following problems when using robolectric unit test:

It has been reported that the resource class cannot be found, so it needs to be added to gradle under the app (the code is manually typed, there may be an error, sorry)

testOptions{
	unitTests{
			includeAndroidResources = true
	}
}

After adding the above code, there is an error in the title, specifically android.test.monitor2… This can’t be found. Each time sync takes a long time, and then report the same error. Refer to the following link article, but it doesn’t help me much.

Ask colleagues for help. After comparing our configurations, we found that the gradle version references are different (gradle/wrapper/gradle wrapper. Properties). The previous references are:

distributionUrl:=https\://service.gradle.org/distributions/gradle-5.4.1-all.zip

Mine is taken directly from the company mapping Maven library. It is a local reference with a lower version:

distributionUrl:=../../../../tools/gradle-4.1-all.zip

I changed the gradle configuration according to her configuration and synced again. The problem was solved.

Solve the problem of springboot and unit test starting applicationrunner

During the execution of unit test, applicationrunner was started unexpectedly, resulting in the initialization of netty server and the failure of unit test execution.

Solution: by setting the profile of bean corresponding to applicationrunner

Add notes to corresponding components:

@Profile(“! test”)

Add notes to unit tests:

@ActiveProfiles(“test”)

The usage of Java JUnit unit test and the solution of initialization error

Usage:
1. Select project – right click – build path – add Libraries – JUnit – next – junit4 – finish
2. Write @ test on the method body to be tested

Note:
1. The test method must be modified with public
2. The return value must be void
3. There can be no parameters in the method
4. There can be no class named test under the package
if the test code is OK, an error is still reported, initialization error is not reported in other classes,
it may be because there is an error method in this class
2 Or there are multiple @ test annotations in a class, one of which adds static or has other errors.
