Servlet和Filter的单元测试

导包：

<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-test</artifactId>
<version>5.2.7.RELEASE</version>
<scope>test</scope>
</dependency>

Servlet单元测试代码：

@Test
public void test(){
MyServlet servlet = new MyServlet();
MockHttpServletRequest req = new MockHttpServletRequest();
MockHttpServletResponse res = new MockHttpServletResponse();
try {
servlet.doPost(req, res);
} catch (Exception e) {
e.printStackTrace();
}
}

Filter单元测试代码：

@Test
public void test(){
MyFilter filter = new MyFilter();
MockFilterConfig config = new MockFilterConfig();
config.addInitParameter("test", "1");
MockHttpServletRequest req = new MockHttpServletRequest();
MockHttpServletResponse res = new MockHttpServletResponse();
MockFilterChain filterChain = new MockFilterChain();
try {
filter.init(config);
filter.doFilter(req, res, filterChain);
} catch (Exception e) {
e.printStackTrace();
}
}
