問題描述

我遇到了一個問題.有時，當我的 JUnit 測試運行時，命令 webDriver.quit();沒有殺死 chromedriver 進程，因此下一個測試無法開始.在這種情況下，我想添加一些可能會在 Linux 上手動終止進程的方法，但我不知道如何獲取 chromedriver 的 PID，因此我可以執(zhí)行以下操作:Runtime.getRuntime().exec(KILL + PID);

I've faced a problem. Sometimes, while my JUnit tests are running, command webDriver.quit(); isn't killing chromedriver process so the next test can't start. In that case I want to add some method which may kill process manually on Linux, but I can't figure out how to get PID of chromedriver so I can do something like: Runtime.getRuntime().exec(KILL + PID);

推薦答案

你可以使用 pgrep 找到 PID，然后殺死它:

You can find PIDs using pgrep and then kill it:

    private void killChromedriver() throws IOException, InterruptedException {
        String command = "pgrep chromedriver";
        Process process = Runtime.getRuntime().exec(command);
        BufferedReader br = new BufferedReader(new InputStreamReader(process.getInputStream()));
        List<String> processIds = getProcessedIds (process, br);
        for (String pid: processIds) {
                Process p = Runtime.getRuntime().exec("kill -9 " + pid);
                p.waitFor();
                p.destroy();
        }
    }
    private List<String> getProcessedIds(Process process, BufferedReader br) throws IOException, InterruptedException {
        process.waitFor();

        List<String> result = new ArrayList<>();
        String processId ;

        while (null != (processId = br.readLine())) {
            result.add(processId);
        }

        process.destroy();
        return result;
    }

更新

另一個更簡單的解決方案似乎是

Another and more simple solution seems to be

    Runtime.getRuntime().exec("pkill chromedriver");
