Question

我有一个servlet：

class MyServlet extends HttpServlet
{
   public void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException
   {
       String one = request.getParameter("one");
       String two = request.getParameter("two");
       addNew(one, two);
   }

   public void addNew(String one, String two){
        // DAO called here to insert a new record
   }

}

我想测试是否在不执行其主体的情况下调用'addNew'。我知道我需要一个测试双，但不知道间谍是否是最好的方法。我想这样做：

class MyServletSpy extends MyServlet
{
   private boolean addNewGotCalled = false;

   @Override
   public void addNew(String one, Integer, two)
   {
       addNewGotCalled = true;
   }

   public boolean addNewWasCalled()
   {
       return this.addNewGotCalled;
   }
}

这是正确的方法吗？我觉得扩展MyServlet是一个愚蠢的奇怪，似乎我允许我的测试有依赖。

很难理解你真正想要测试的内容但是如果你想测试你的Servlet的行为，你可以试着看看Jetty：https://webtide.com/unit-test-servlets-with-jetty/

感谢您的澄清。在您的情况下，一种解决方案是使用addNew来测试成功调用<dependency> <groupId>org.mockito</groupId> <artifactId>mockito-all</artifactId> <version>1.9.5</version> <scope>test</scope> </dependency>方法。

首先你需要mockito依赖：

spy

然后您可以使用/** * Test of {@link MyServlet} class * @author rouliboy */ public class MyServletTest { @Test public void testAddNewCall() throws ServletException, IOException { // Initialization MyServlet myServlet = new MyServlet(); myServlet = Mockito.spy(myServlet); final HttpServletRequest mockHttpServletRequest = Mockito.mock(HttpServletRequest.class); final HttpServletResponse mockHttpServletResponse = Mockito.mock(HttpServletResponse.class); Mockito.when(mockHttpServletRequest.getParameter("one")).thenReturn("oneReturn"); Mockito.when(mockHttpServletRequest.getParameter("two")).thenReturn("twoReturn"); // Test myServlet.doPost(mockHttpServletRequest, mockHttpServletResponse); // Verification Mockito.verify(myServlet).addNew("oneReturn", "twoReturn"); } }方法测试您的Servlet：

spy

<强>说明

首先我们myServlet = Mockito.spy(myServlet);使用Servlet：

spy

使用HttpServletRequest，我们可以检查Servlet中调用的方法。

然后我们模拟HttpServletResponse方法的doPost和HttpServletRequest.getParameter(...)输入。使用模拟，我们可以通过Mockito.when(mockHttpServletRequest.getParameter("one")).thenReturn("oneReturn"); Mockito.when(mockHttpServletRequest.getParameter("two")).thenReturn("twoReturn");定义返回值的行为：

doPost

在调用addNew方法后，我们验证是否已成功调用Mockito.verify(myServlet).addNew("oneReturn", "twoReturn");：

#include <SpritzCipher.h> String salt = "fkllrnjnfd"; int randNumber; String valorConcat; void randomico() { //Serial.begin(9600); randomSeed(analogRead(0)); // Starts the list of random values randNumber = random(100); // Draw a number from 0 to 99 valorConcat = String(randNumber) + salt; //Serial.println(valorConcat); // Sends the value of randNumber to the serial delay(500); // espera 500 ms } /* Data to input */ const byte testData[12] = {randomico}; /* Test vectors */ /* Data = 'testData' hash test vectors */ const byte testVector[32] = { 0xff, 0x8c, 0xf2, 0x68, 0x09, 0x4c, 0x87, 0xb9, 0x5f, 0x74, 0xce, 0x6f, 0xee, 0x9d, 0x30, 0x03, 0xa5, 0xf9, 0xfe, 0x69, 0x44, 0x65, 0x3c, 0xd5, 0x0e, 0x66, 0xbf, 0x18, 0x9c, 0x63, 0xf6, 0x99 }; void testFunc(const byte ExpectedOutput[32], const byte *data, byte dataLen) { byte hashLen = 32; /* 256-bit */ byte digest[hashLen]; /* Output buffer */ byte digest_2[hashLen]; /* Output buffer for chunk by chunk API */ spritz_ctx hash_ctx; /* the CTX for chunk by chunk API */ unsigned int i; /* Print input */ for (i = 0; i < dataLen; i++) { Serial.write(data[i]); } Serial.println(); spritz_hash_setup(&hash_ctx); /* For easy test: code add a byte each time */ for (i = 0; i < dataLen; i++) { spritz_hash_update(&hash_ctx, data + i, 1); } spritz_hash_final(&hash_ctx, digest_2, hashLen); spritz_hash(digest, hashLen, data, dataLen); for (i = 0; i < sizeof(digest); i++) { if (digest[i] < 0x10) { /* To print "0F" not "F" */ Serial.write('0'); } Serial.print(digest[i], HEX); } /* Check the output */ if (spritz_compare(digest, ExpectedOutput, sizeof(digest)) || spritz_compare(digest_2, ExpectedOutput, sizeof(digest_2))) { /* If the output is wrong "Alert" */ digitalWrite(LED_BUILTIN, HIGH); /* Turn pin LED_BUILTIN On (Most boards have this LED connected to digital pin 13) */ Serial.println("\n** WARNING: Output != Test_Vector **"); } Serial.println(); } void setup() { /* Initialize serial and wait for port to open */ Serial.begin(9600); while (!Serial) { ; /* Wait for serial port to connect. Needed for Leonardo only */ } /* initialize digital pin LED_BUILTIN (Most boards have this LED connected to digital pin 13) as an output */ pinMode(LED_BUILTIN, OUTPUT); digitalWrite(LED_BUILTIN, LOW); } void loop() { Serial.println("[Spritz spritz_hash*() test]\n"); /* Data: arcfour */ testFunc(testVector, testData, sizeof(testData)); delay(5000); /* Wait 5s */ Serial.println(); }

但是，我认为最好完全测试你的Servlet（例如使用Jetty并模拟你的DAO），而不仅仅是测试你的addNew方法是否被调用。

如何测试我的servlet是否调用了某种方法？
