使用 gradlew 运行大量测试

Question

我有一个包含大约 500-700 个测试的应用程序，我需要使用运行这些测试

./gradlew clean build

一些测试会带来上下文。无论我尝试多少次更改 build.gradle 中 gradler 测试的设置，测试都会失败并出现错误

OutOfMemory

，初步日志显示以下内容：

build.gradle

设置是这样的

test {
    useJUnitPlatform()
    maxParallelForks = 1          
    forkEvery = 10             


    jvmArgs = [
            '-Xmx2g',
            '-XX:MaxMetaspaceSize=512m',
            '-XX:+UseG1GC',
            '-XX:G1HeapRegionSize=8m',
            '-XX:InitiatingHeapOccupancyPercent=20',
            '-XX:ConcGCThreads=1',
            '-XX:ParallelGCThreads=1',
            '-XX:MaxGCPauseMillis=300',
            '-XX:+HeapDumpOnOutOfMemoryError', 
            '-XX:HeapDumpPath=build/heapdumps',
            '-Xlog:gc*:build/gc.log'   
    ]
    systemProperties = [
            "feign.client.config.default.connectTimeout"   : "5000",
            "feign.client.config.default.readTimeout"      : "5000",
            "feign.httpclient.maxConnections"              : "3",
            "hikari.maximumPoolSize"                       : "2"
    ]
}

有人告诉我如何设置吗？

您需要为全局或每个客户端设置 Open Feign 的超时时间。
