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

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
    }
}

其他回答

以下是我的观点:

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

tasks.withType(Test) {
    testLogging {
        // set options for log level LIFECYCLE
        events TestLogEvent.FAILED,
               TestLogEvent.PASSED,
               TestLogEvent.SKIPPED,
               TestLogEvent.STANDARD_OUT
        exceptionFormat TestExceptionFormat.FULL
        showExceptions true
        showCauses true
        showStackTraces true

        // set options for log level DEBUG and INFO
        debug {
            events TestLogEvent.STARTED,
                   TestLogEvent.FAILED,
                   TestLogEvent.PASSED,
                   TestLogEvent.SKIPPED,
                   TestLogEvent.STANDARD_ERROR,
                   TestLogEvent.STANDARD_OUT
            exceptionFormat TestExceptionFormat.FULL
        }
        info.events = debug.events
        info.exceptionFormat = debug.exceptionFormat

        afterSuite { desc, result ->
            if (!desc.parent) { // will match the outermost suite
                def output = "Results: ${result.resultType} (${result.testCount} tests, ${result.successfulTestCount} passed, ${result.failedTestCount} failed, ${result.skippedTestCount} skipped)"
                def startItem = '|  ', endItem = '  |'
                def repeatLength = startItem.length() + output.length() + endItem.length()
                println('\n' + ('-' * repeatLength) + '\n' + startItem + output + endItem + '\n' + ('-' * repeatLength))
            }
        }
    }
}

添加此构建。Gradle停止Gradle吞下stdout和stderr。

test {
    testLogging.showStandardStreams = true
}

这里有记录。

如果你有一个用Kotlin DSL编写的build.gradle.kts,你可以用它打印测试结果(我正在开发一个Kotlin多平台项目,没有应用“java”插件):

tasks.withType<AbstractTestTask> {
    afterSuite(KotlinClosure2({ desc: TestDescriptor, result: TestResult ->
        if (desc.parent == null) { // will match the outermost suite
            println("Results: ${result.resultType} (${result.testCount} tests, ${result.successfulTestCount} successes, ${result.failedTestCount} failures, ${result.skippedTestCount} skipped)")
        }
    }))
}

合并Shubham的伟大答案和JJD使用enum而不是字符串

tasks.withType(Test) {
   testLogging {
       // set options for log level LIFECYCLE
       events TestLogEvent.PASSED,
            TestLogEvent.SKIPPED, TestLogEvent.FAILED, TestLogEvent.STANDARD_OUT
       showExceptions true
       exceptionFormat TestExceptionFormat.FULL
       showCauses true
       showStackTraces true

    // set options for log level DEBUG and INFO
       debug {
        events TestLogEvent.STARTED, TestLogEvent.PASSED, TestLogEvent.SKIPPED, TestLogEvent.FAILED, TestLogEvent.STANDARD_OUT, TestLogEvent.STANDARD_ERROR
        exceptionFormat TestExceptionFormat.FULL
       }
       info.events = debug.events
       info.exceptionFormat = debug.exceptionFormat

       afterSuite { desc, result ->
           if (!desc.parent) { // will match the outermost suite
               def output = "Results: ${result.resultType} (${result.testCount} tests, ${result.successfulTestCount} successes, ${result.failedTestCount} failures, ${result.skippedTestCount} skipped)"
               def startItem = '|  ', endItem = '  |'
               def repeatLength = startItem.length() + output.length() + endItem.length()
               println('\n' + ('-' * repeatLength) + '\n' + startItem + output + endItem + '\n' + ('-' * repeatLength))
           }
       }
   }
}

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)")
                    }
                })
            )
        }
    }
}
