Inspiré par cette tâche soignée de TestNG et cette question SO Je me suis dit que j'allais préparer quelque chose de rapide pour relancer les tests JUnit qui ont échoué depuis Gradle.
Mais après avoir cherché pendant un certain temps, je n'ai rien trouvé d'analogue qui soit aussi pratique.
J'ai trouvé ce qui suit, qui semble fonctionner assez bien et qui ajoute un <testTaskName>Rerun
pour chaque tâche de type Test
dans mon projet.
import static groovy.io.FileType.FILES
import java.nio.file.Files
import java.nio.file.Paths
// And add a task for each test task to rerun just the failing tests
subprojects {
afterEvaluate { subproject ->
// Need to store tasks in static temp collection, else new tasks will be picked up by live collection leading to StackOverflow
def testTasks = subproject.tasks.withType(Test)
testTasks.each { testTask ->
task "${testTask.name}Rerun"(type: Test) {
group = 'Verification'
description = "Re-run ONLY the failing tests from the previous run of ${testTask.name}."
// Depend on anything the existing test task depended on
dependsOn testTask.dependsOn
// Copy runtime setup from existing test task
testClassesDirs = testTask.testClassesDirs
classpath = testTask.classpath
// Check the output directory for failing tests
File textXMLDir = subproject.file(testTask.reports.junitXml.destination)
logger.info("Scanning: $textXMLDir for failed tests.")
// Find all failed classes
Set<String> allFailedClasses = [] as Set
if (textXMLDir.exists()) {
textXMLDir.eachFileRecurse(FILES) { f ->
// See: http://marxsoftware.blogspot.com/2015/02/determining-file-types-in-java.html
String fileType
try {
fileType = Files.probeContentType(f.toPath())
} catch (IOException e) {
logger.debug("Exception when probing content type of: $f.")
logger.debug(e)
// Couldn't determine this to be an XML file. That's fine, skip this one.
return
}
logger.debug("Filetype of: $f is $fileType.")
if (['text/xml', 'application/xml'].contains(fileType)) {
logger.debug("Found testsuite file: $f.")
def testSuite = new XmlSlurper().parse(f)
def failedTestCases = testSuite.testcase.findAll { testCase ->
testCase.children().find { it.name() == 'failure' }
}
if (!failedTestCases.isEmpty()) {
logger.info("Found failures in file: $f.")
failedTestCases.each { failedTestCase ->
def className = failedTestCase['@classname']
logger.info("Failure: $className")
allFailedClasses << className.toString()
}
}
}
}
}
if (!allFailedClasses.isEmpty()) {
// Re-run all tests in any class with any failures
allFailedClasses.each { c ->
def testPath = c.replaceAll('\\.', '/') + '.class'
include testPath
}
doFirst {
logger.warn('Re-running the following tests:')
allFailedClasses.each { c ->
logger.warn(c)
}
}
}
outputs.upToDateWhen { false } // Always attempt to re-run failing tests
// Only re-run if there were any failing tests, else just print warning
onlyIf {
def shouldRun = !allFailedClasses.isEmpty()
if (!shouldRun) {
logger.warn("No failed tests found for previous run of task: ${subproject.path}:${testTask.name}.")
}
return shouldRun
}
}
}
}
}
Existe-t-il un moyen plus simple de le faire à partir de Gradle ? Existe-t-il un moyen de faire en sorte que JUnit produise une liste consolidée des échecs afin que je n'aie pas à avaler les rapports XML ?
J'utilise JUnit 4.12 et Gradle 4.5.
