Sometimes, you need to verify the web Background pressure during testing. If you want testers to enter and submit forms continuously, it may be difficult to solve this problem.
For example, if you have a web project whose homepage index. jsp:
[Html]
<% @ Page language = "java" import = "java. util. *" pageEncoding = "UTF-8" %>
<%
String path = request. getContextPath ();
String basePath = request. getScheme () + ": //" + request. getServerName () + ":" + request. getServerPort () + path + "/";
%>
<! Doctype html public "-// W3C // dtd html 4.01 Transitional // EN">
<Html>
<Head>
<Base href = "<% = basePath %>">
<Title> My JSP 'index. jsp 'starting page </title>
<Meta http-equiv = "pragma" content = "no-cache">
<Meta http-equiv = "cache-control" content = "no-cache">
<Meta http-equiv = "expires" content = "0">
<Meta http-equiv = "keywords" content = "keyword1, keyword2, keyword3">
<Meta http-equiv = "description" content = "This is my page">
<! --
<Link rel = "stylesheet" type = "text/css" href = "styles.css">
-->
</Head>
<Body>
<Form action = "<% = path %>/LoginServ" method = "post" name = "loginForm" id = "loginForm">
<Table width = "250" border = "0">
<Tr>
<Td> account: </td> <input type = "text" name = "username" id = "username"/> </td>
</Tr>
<Tr>
<Td> password: </td> <input type = "password" name = "pass" id = "pass"/> </td>
</Tr>
<Tr>
<Td colspan = 2> <input type = "submit" value = "login" name = "testlogin"/> </td>

</Table>
</Form>

After the project is deployed and run, we compile the test code and simulate the form to submit the data:
[Java]
Package com. test;
Import com.gargoylesoftware.html unit. WebClient;
Import com.gargoylesoftware.htmlunit.html. HtmlForm;
Import com.gargoylesoftware.htmlunit.html. HtmlPage;
Import com.gargoylesoftware.htmlunit.html. HtmlPasswordInput;
Import com.gargoylesoftware.htmlunit.html. HtmlSubmitInput;
Import com.gargoylesoftware.htmlunit.html. HtmlTextInput;
Public class Test {
Public static void submittingForm () throws Exception {
Final WebClient webClient = new WebClient ();
// 1. Obtain a page to be tested
Final HtmlPage page1 = webClient. getPage ("http: // localhost: 8081/HtmlUnitTest ");
// 2. Obtain the form on the page
Final HtmlForm form = page1.getForms (). get (0 );
// 3. Obtain the elements on the page
Final HtmlSubmitInput button = form. getInputByName ("testlogin ");
Final HtmlTextInput textField = form. getInputByName ("username ");
Final HtmlPasswordInput pass = form. getInputByName ("pass ");
// 4. assign values to elements
TextField. setValueAttribute ("I am Zhang San ");
Pass. setValueAttribute ("routon ");
// 5. Submit
Button. click ();
}
Public static void main (String [] args ){
Try {
SubmittingForm ();
} Catch (Exception e ){
E. printStackTrace ();
}
}
