Testes contínuos

Saiba como usar o teste contínuo em sua aplicação Quarkus.

1. Pré-requisitos

Para concluir este guia, você precisa:

Cerca de 15 minutos
Um IDE
JDK 17+ installed with JAVA_HOME configured appropriately
Apache Maven 3.9.9
Opcionalmente, o Quarkus CLI se você quiser usá-lo
Opcionalmente, Mandrel ou GraalVM instalado e configurado apropriadamente se você quiser criar um executável nativo (ou Docker se você usar uma compilação de contêiner nativo)
The completed greeter application from the Getting Started Guide

2. Introdução

Quarkus supports continuous testing, where tests run immediately after code changes have been saved. This allows you to get instant feedback on your code changes. Quarkus detects which tests cover which code, and uses this information to only run the relevant tests when code is changed.

3. Solução

Start the Getting Started application (or any other application) using:

CLI

quarkus dev

Maven

./mvnw quarkus:dev

Gradle

./gradlew --console=plain quarkusDev

Quarkus will start in development mode as normal, but down the bottom of the screen you should see the following:

--
Tests paused, press [r] to resume, [h] for more options>

Press r and the tests will start running. You should see the status change down the bottom of the screen as they are running, and it should finish with:

--
Tests all passed, 2 tests were run, 0 were skipped. Tests took 1470ms.
Press [r] to re-run, [v] to view full results, [p] to pause, [h] for more options>

If you want continuous testing to start automatically you can set quarkus.test.continuous-testing=enabled in application.properties. If you don’t want it at all you can change this to disabled.

Now you can start making changes to your application. Go into the GreetingResource and change the hello endpoint to return "hello world", and save the file. Quarkus should immediately re-run the test, and you should get output similar to the following:

2021-05-11 14:21:34,338 ERROR [io.qua.test] (Test runner thread) Test GreetingResourceTest#testHelloEndpoint() failed
: java.lang.AssertionError: 1 expectation failed.
Response body doesn't match expectation.
Expected: is "hello"
  Actual: hello world

	at io.restassured.internal.ValidatableResponseImpl.body(ValidatableResponseImpl.groovy)
	at org.acme.getting.started.GreetingResourceTest.testHelloEndpoint(GreetingResourceTest.java:21)


--
Test run failed, 2 tests were run, 1 failed, 0 were skipped. Tests took 295ms
Press [r] to re-run, [v] to view full results, [p] to pause, [h] for more options>

Change it back and the tests will run again.

4. Controlling Continuous Testing

There are various hotkeys you can use to control continuous testing. Pressing h will display the following list of commands:

The following commands are available:
[r] - Re-run all tests
[f] - Re-run failed tests
[b] - Toggle 'broken only' mode, where only failing tests are run (disabled)
[v] - Print failures from the last test run
[p] - Pause tests
[o] - Toggle test output (disabled)
[i] - Toggle instrumentation based reload (disabled)
[l] - Toggle live reload (enabled)
[s] - Force restart
[h] - Display this help
[q] - Quit

These are explained below:

[r] - Re-run all tests: This will re-run every test
[f] - Re-run failed tests: This will re-run every failing test
[b] - Toggle 'broken only' mode, where only failing tests are run: Broken only mode will only run tests that have previously failed, even if other tests would normally be affected by a code change. This can be useful if you are modifying code that is used by lots of tests, but you only want to focus on debugging the failing one.
[v] - Print failures from the last test run: Prints the failures to the console again, this can be useful if there has been lots of console output since the last run.
[p] - Pause tests: Temporarily stops running tests. This can be useful if you are making lots of changes, and don’t want feedback until they are all done.
[o] - Toggle test output: By default test output is filtered and not displayed on the console, so that test output and dev mode output is not interleaved. Enabling test output will print output to the console when tests are run. Even when output is disabled the filtered output is saved and can be viewed in the Dev UI.
[i] - Toggle instrumentation based reload: This is not directly related to testing, but allows you to toggle instrumentation based reload. This will allow live reload to avoid a restart if a change does not affect the structure of a class, which gives a faster reload and allows you to keep state.
[l] - Toggle live reload: This is not directly related to testing, but allows you to turn live reload on and off.
[s] - Force restart: This will force a scan for changed files, and will perform a live reload with and changes. Note that even if there are no changes the application will still restart. This will still work even if live reload is disabled.

5. Continuous Testing Without Dev Mode

It is possible to run continuous testing without starting dev mode. This can be useful if dev mode will interfere with your tests (e.g. running wiremock on the same port), or if you only want to develop using tests. To start continuous testing mode run mvn quarkus:test.

The Dev UI is not available when running in continuous testing mode, as this is provided by dev mode.

6. Multi-module Projects

Note that continuous testing supports multi-module projects, so tests in modules other than the application can still be run when files are changed. The modules that are run can be controlled using config as listed below.

This is enabled by default, and can be disabled via quarkus.test.only-test-application-module=true.

7. Configuring Continuous Testing

Continuous testing supports multiple configuration options that can be used to limit the tests that are run, and to control the output. The configuration properties are shown below:

Propriedade de Configuração Fixa no Momento da Compilação - Todas as outras propriedades de configuração podem ser sobrepostas em tempo de execução.

Configuration property	Tipo	Padrão
`quarkus.test.continuous-testing` If continuous testing is enabled. The default value is 'paused', which will allow you to start testing from the console or the Dev UI, but will not run tests on startup. If this is set to 'enabled' then testing will start as soon as the application has started. If this is 'disabled' then continuous testing is not enabled, and can’t be enabled without restarting the application.

`quarkus.test.flat-class-path` Changes tests to use the 'flat' ClassPath used in Quarkus 1.x versions. This means all Quarkus and test classes are loaded in the same ClassLoader, however it means you cannot use continuous testing. Note that if you find this necessary for your application then you may also have problems running in development mode, which cannot use a flat class path.

`quarkus.test.hang-detection-timeout` Configures the hang detection in @QuarkusTest. If no activity happens (i.e. no test callbacks are called) over this period then QuarkusTest will dump all threads stack traces, to help diagnose a potential hang. Note that the initial timeout (before Quarkus has started) will only apply if provided by a system property, as it is not possible to read all config sources until Quarkus has booted. Environment variable: `QUARKUS_TEST_HANG_DETECTION_TIMEOUT` Show more	Duration	`10M`
`quarkus.test.type` The type of test to run, this can be either: quarkus-test: Only runs `@QuarkusTest` annotated test classes unit: Only runs classes that are not annotated with `@QuarkusTest` all: Runs both, running the unit tests first Environment variable: `QUARKUS_TEST_TYPE` Show more	`unit`, `quarkus-test`, `all`	`all`

About the Duration format

To write duration values, use the standard java.time.Duration format. See the Duration#parse() Java API documentation for more information.

Você também pode usar um formato simplificado, começando com um número:

Se o valor for apenas um número, ele representará o tempo em segundos.
Se o valor for um número seguido de 'ms', ele representa o tempo em milissegundos.

Em outros casos, o formato simplificado é traduzido para o formato 'java.time.Duration' para análise:

Se o valor for um número seguido de 'h', 'm' ou 's', ele é prefixado com 'PT'.
Se o valor for um número seguido de 'd', ele é prefixado com 'P'.
