Concordion - assertFalse Command

Concordion assertFalse command is used when the fixture needs to know the expected result in order to perform a test.

Consider the following requirement −

User Name : Robert De
The User name does not start with S.

If we want a test to be executed on the User Name and check that the user name does not start with S.

<p>User Name :<span concordion:set = "#userName">Robert De</span></p>
<p>The User name <span concordion:assertFalse = "#userName.startsWith(#letter)">does not start
   with <b concordion:set = "#letter">S</b></span>.</p>  

When Concordion parses the document, it will set a temporary variable #userName to be the value "Robert De". Then, it will check if the userName starts with the letter specified by #letter variable set in next command.


Let us have a working Eclipse IDE in place and follow the steps given below to create a Concordion application −

Step Description
1 Create a project with a name concordion and create a package com.tutorialspoint under the src folder in the created project.
2 Add the required Concordion libraries using Add External JARs option as explained in the Concordion - First Application chapter.
3 Create Java class System under the com.tutorialspoint package.
4 Create Fixture class SystemFixture under the specs.tutorialspoint package.
5 Create Specification html System.html under the specs.tutorialspoint package.
6 The final step is to create the content of all the Java files and specification file and run the application as explained below.

Here is the content of the file −

package com.tutorialspoint;
public class System {   

Following is the content of the file −

package specs.tutorialspoint;

import org.concordion.integration.junit4.ConcordionRunner;
import org.junit.runner.RunWith;


public class SystemFixture {

Following is the content of the System.html file −

<html xmlns:concordion = "">
      <link href = "../concordion.css" rel = "stylesheet" type = "text/css" />

      <h1>System Specifications</h1>
      <p>We are building specifications for our online order tracking application.</p>
      <p>Following is the requirement to split full name of a logged in user to its 
         constituents by splitting name by whitespace:</p>
      <div class = "example">      
         <p>User Name :<span concordion:set = "#userName">Robert De</span></p>
         <p>The User name <span concordion:assertFalse = "#userName.startsWith(#letter)">
            does not start with <b concordion:set = "#letter">


Once you are done with creating source and specification files, let us run the application as JUnit Test. If everything is fine with your application, then it will produce the following result −

Successes: 1, Failures: 0

System.html is the output of Concordion test run.
