JUnit Tests for CSVReader

This repository contains JUnit tests for the CSVReader assignment.

• EasyCSVReaderTest.java - uses test cases like in the assignment sheet, with some tests that CSVReader skips blank lines and comment lines.

• BigCSVReaderTest.java - more detailed tests of CSVReader.

These tests require:

1. You have a CSVReader.java class in the ku.util package, and it has the constructor and methods specified in the assignment.
2. The JUnit 4 libraries on your project classpath.

Eclipse, Netbeans, and BlueJ come with the JUnit 4 library. For Eclipse nad Netbeans, when you add the JUnit test source files to your project you will get an error message about missing classes.
Use "fix project setup" (or "Configure Build Path") to add JUnit 4 to your project.

In Eclipse, if your project contains JUnit tests but doesn't have the JUnit library, Eclipse will flag errors because the project doesn't have the JUnit library. Open one of the JUnit test sources and put the cursor on a line that has an error (like import org.junit.*). Press CTRL-1 which means "quick fix". Eclipse will show a dialog of fixes. Choose "Fix project setup".

Eclipse, Netbeans, IntelliJ

Most developers use two "source" directories in a project:

• src/ - contains the main source code
• test/ - contains test code

If you want to do this, you have to tell the IDE to use 2 source dirs.

• First, add the test code to a folder named test. The test folder should have the same directory structure as your main src folder. (See below)
• In Eclipse, open the dialog for Project -> Properties and choose "Java Build Path". Select the "Source" tab. Click "Add Folder..." and add the test folder. Exit the dialog.
• Now, Eclipse will compile and run files in both the src and test folders.
• Other IDE are similar: open the project configuration dialog and specify that it should use test as a source folder.

Add these Tests to your Project

Please don't "commit" the JUnit test files to your Git repo.

1. Just add the files to project (the simple way)

Just copy the java files to your project source directory (or test/ source directory). You should have files like this, relative to your project source root:

ku/util/
ku/util/BigCSVReaderTest.java
ku/util/EasyCSVReaderTest.java
ku/util/TestRunner.java

If the test code is in a separate test/ directory, then you'll have:

test/ku/util/
test/ku/util/BigCSVReaderTest.java
test/ku/util/EasyCSVReaderTest.java
test/ku/util/TestRunner.java

2. Using git submodule (requires separate src/ and test/ dirs)

The Git repository for CSVReaderTest is structured as a Git submodule. Git submodules let you add a Git repository inside another Git repository, but keep the two sets of files separate. Here are the steps:

1. change directory to your CSVReader project

   > cd /workspace/csvreader
   

2. add the CSVReaderTest as a submodule, and put the files in a subdirectory named "test". IMPORTANT: don't forget the "test" parameter on command line.

   > git submodule add https://github.com/OOP2017/CSVReaderTest.git test
   

   This should add files to the "test" directory.

3. If you don't have any files in the test directory then do this:

   > git submodule init
   > git submodule update
   

Two Ways to Run the Tests

• Run as JUnit tests in your IDE. Usually you right-click on the test file and choose "Run JUnit test".

• Run TestRunner as an ordinary Java application. This will run both test classes.
