我想看测试结果(系统)。out/err,来自正在测试的组件的日志消息),因为它们运行在我运行的同一控制台:

gradle test

不要等到测试完成才查看测试报告(测试报告仅在测试完成时生成,因此在运行测试时不能“尾部-f”任何内容)


当前回答

我为Kotlin DSL编写了一个测试记录器。您可以将此块放在项目范围build.gradle.kts文件中。

subprojects {
    tasks.withType(Test::class.java) {
        testLogging {
            showCauses = false
            showExceptions = false
            showStackTraces = false
            showStandardStreams = false

            val ansiReset = "\u001B[0m"
            val ansiGreen = "\u001B[32m"
            val ansiRed = "\u001B[31m"
            val ansiYellow = "\u001B[33m"

            fun getColoredResultType(resultType: ResultType): String {
                return when (resultType) {
                    ResultType.SUCCESS -> "$ansiGreen $resultType $ansiReset"
                    ResultType.FAILURE -> "$ansiRed $resultType $ansiReset"
                    ResultType.SKIPPED -> "$ansiYellow $resultType $ansiReset"
                }
            }

            afterTest(
                KotlinClosure2({ desc: TestDescriptor, result: TestResult ->
                    println("${desc.className} | ${desc.displayName} = ${getColoredResultType(result.resultType)}")
                })
            )

            afterSuite(
                KotlinClosure2({ desc: TestDescriptor, result: TestResult ->
                    if (desc.parent == null) {
                        println("Result: ${result.resultType} (${result.testCount} tests, ${result.successfulTestCount} passed, ${result.failedTestCount} failed, ${result.skippedTestCount} skipped)")
                    }
                })
            )
        }
    }
}

其他回答

对于那些使用Kotlin DSL的人来说,一个更全面的回应是:

subprojects {
    // all the other stuff
    // ...
    tasks.named<Test>("test") {
        useJUnitPlatform()
        setupTestLogging()
    }
}

fun Test.setupTestLogging() {
    testLogging {
        events(
            org.gradle.api.tasks.testing.logging.TestLogEvent.FAILED,
            org.gradle.api.tasks.testing.logging.TestLogEvent.PASSED,
            org.gradle.api.tasks.testing.logging.TestLogEvent.SKIPPED,
            org.gradle.api.tasks.testing.logging.TestLogEvent.STANDARD_OUT,
        )
        exceptionFormat = org.gradle.api.tasks.testing.logging.TestExceptionFormat.FULL
        showExceptions = true
        showCauses = true
        showStackTraces = true

        addTestListener(object : TestListener {
            override fun beforeSuite(suite: TestDescriptor) {}
            override fun beforeTest(testDescriptor: TestDescriptor) {}
            override fun afterTest(testDescriptor: TestDescriptor, result: TestResult) {}
            override fun afterSuite(suite: TestDescriptor, result: TestResult) {
                if (suite.parent != null) { // will match the outermost suite
                    val output = "Results: ${result.resultType} (${result.testCount} tests, ${result.successfulTestCount} passed, ${result.failedTestCount} failed, ${result.skippedTestCount} skipped)"
                    val startItem = "|  "
                    val endItem = "  |"
                    val repeatLength = startItem.length + output.length + endItem.length
                    val messages = """
                        ${(1..repeatLength).joinToString("") { "-" }}
                        $startItem$output$endItem
                        ${(1..repeatLength).joinToString("") { "-" }}
                    """.trimIndent()
                    println(messages)
                }
            }
        })
    }
}

这应该产生一个接近@odemolliens answers的输出。

'test'任务不适用于Android插件,对于Android插件使用以下方法:

// Test Logging
tasks.withType(Test) {
    testLogging {
        events "started", "passed", "skipped", "failed"
    }
}

详见:https://stackoverflow.com/a/31665341/3521637

作为Shubham的精彩回答的后续,我建议使用枚举值而不是字符串。请查看TestLogging类的文档。

import org.gradle.api.tasks.testing.logging.TestExceptionFormat
import org.gradle.api.tasks.testing.logging.TestLogEvent

tasks.withType(Test) {
    testLogging {
        events TestLogEvent.FAILED,
               TestLogEvent.PASSED,
               TestLogEvent.SKIPPED,
               TestLogEvent.STANDARD_ERROR,
               TestLogEvent.STANDARD_OUT
        exceptionFormat TestExceptionFormat.FULL
        showCauses true
        showExceptions true
        showStackTraces true
    }
}

添加此构建。Gradle停止Gradle吞下stdout和stderr。

test {
    testLogging.showStandardStreams = true
}

这里有记录。

如果你正在使用jupiter,没有一个答案工作,请考虑验证它是否正确设置:

test {
    useJUnitPlatform()
    outputs.upToDateWhen { false }
}

dependencies {
    testImplementation 'org.junit.jupiter:junit-jupiter-api:5.7.0'
    testRuntimeOnly 'org.junit.jupiter:junit-jupiter-engine:5.7.0'
}
