Selenium，单击一个按钮并循环迭代循环失败

Question

我有一个测试

public class SeleniumForh extends BaseTest {

    private static List<String> FNR;
    private static final int THREAD_COUNT = 1;

    private static Set<String> THREADS = Collections.synchronizedSet(new HashSet<String>());

    static {
        List<String> fnr = new ArrayList<String>();
        try {
            BufferedReader reader = new BufferedReader(new InputStreamReader(SeleniumManntallskryss.class.getResourceAsStream("/fnr")));
            String line;
            while ((line = reader.readLine()) != null) {
                fnr.add(line);
            }
            FNR = Collections.synchronizedList(fnr);
        } catch (IOException e) {
            e.printStackTrace();
        }
    }


    public SeleniumForhandstemmer(String platform, String browserName, String browserVersion) {
        super(platform, browserName, browserVersion);
}

    @Parameterized.Parameters
    public static LinkedList<String[]> getEnvironments() throws Exception {
        LinkedList<String[]> env = new LinkedList<String[]>();


        for (int i = 0; i <THREAD_COUNT; i++) {
            env.add(new String[]{"ANY", "firefox", "35"});
        }
        return env;
    }

    @Test

}

问题是当运行secound iteratoion时，我要点击的按钮只是在正在运行的浏览器中用方框标记，而不是cliked。这种情况发生在第二次（不是第一次迭代），我尝试在迭代之间休眠，并且还确认按钮我发现，所以问题是点击功能。而且我可以看到它试图点击，因为正方形在buttoon周围出现。
