Question

我使用testng和htmlUnitDriver运行selenium测试。我为所有测试使用一个webDriver实例。我只是在每个测试类之后注销并清除cookie driver.manage().deleteAllCookies()（删除cookie本身不负责我为此测试）

所以基本上发生的是：

driver.get(url1);
... login to Single Page App ...
driver ... pseudo ... find logout-element and click logout
driver.manage().deleteAllCokies();
driver.get(url1);
... input credentials ...
loginForm.submit();

这会导致以下异常：

删除该文件发生在第二次接听电话上。我很乐意就可能导致这种情况的原因提出建议。

这是我使用的硒maven依赖：

    <dependency>
        <groupId>org.seleniumhq.selenium</groupId>
        <artifactId>selenium-java</artifactId>
        <version>2.45.0</version>
    </dependency>

此错误是因为缓存了WebResponse，并且在获取新页面时清除旧页面并删除其本地文件（默认情况下内容大于500 KB）。

您可以使用以下内容直到修复此问题。

    WebDriver driver = new HtmlUnitDriver() {
        @Override
        protected WebClient getWebClient() {
            WebClient c = super.getWebClient();
            c.getCache().setMaxSize(0);
            return c;
        }
    };

在第二个.get（url）上使用HTMLUnitDriver ScriptException（找不到tmp文件）的Selenium
