TestNG超時測試


在本教學中,我們將演示如何在TestNG中執行超時測試。 「超時」表示如果單元測試花費的時間超過指定的毫秒數,那麼TestNG將會中止它並將其標記為失敗。

「超時」也可用於效能測試,以確保方法在合理的時間內返回。

建立一個名稱為:TimeoutTest 的 Maven 專案,其結構如下所示 -

建立一個測試類:TestTimeout.java,其程式碼如下 -

package com.yiibai;

import org.testng.annotations.Test;

public class TestTimeout {

    @Test(timeOut = 5000) // time in mulliseconds
    public void testThisShouldPass() throws InterruptedException {
        Thread.sleep(4000);
    }

    @Test(timeOut = 1000)
    public void testThisShouldFail() {
        while (true){
            // do nothing
        }

    }

}

執行上面程式碼,得到以下結果 -
