Combinatorial Testing Tools
In this section, we will be discussing some easy-to-use, free, and popular combinatorial testing tools.
1. Pairwise Pict Online
This tool is the simplest to use because we just have to write the test factors and constraints (if any) and the test configurations are generated. This tool allows us to write the constraints using an If-Then format as shown below. It is a good tool for beginners to start with combinatorial testing.

2. CAGen for covering array generator
This tool gives a bit more functionality and features as compared to the previous tool. Firstly, it allows us to create multiple input parameter models instead of just one like in the previous tool. Also, we can save these models as well and export them to a different type of files. It also gives the user an option to import input configuration models. Another advantage of this tool is that it can use three different algorithms (FIPOG, FIPOG-F, FIPOG-F2) to generate the combinatorial object array.
In this tool, factors and levels have to be added one by one. But before that, these steps are to be followed:
- Click here to open the CAGen tool.
- Create a new workspace and give it a relevant name.
- Now click on the workspace created and you will be able to see an Input Parameter Model on your screen.
- Enter factors, their levels, and the cardinality (number of levels) in this model.
- After all factors with their levels have been added to the input parameter model, click on the ‘generate button’ on the left panel to generate test configurations.
3. Pairwiser
This tool requires a user account login. After you have logged in, you can use this tool for free. Just like the CAGen tool, Pairwiser also requires one by one to enter all factors and their values. Similarly, constraints can be entered too in the format of if-then.
Unlike other tools, Pairwiser provides a wide range of functionalities and features that one can explore in combinatorial testing.
- The tool comes with a visualizer that shows the coverage of each test case that is added to the test suite.
- Another amazing feature is the generation of test scripts. If you want to perform combinatorial testing for your application, then you can simply use these test scripts for detailed evaluation. The test scripts can be modified according to our needs using numerous options available in the tool.
- Pairwiser is quite a popular tool in the case of combinatorial testing (pairwise-testing) as it offers a faster pairwise algorithm in the market.

4. Testcover.com
Another intuitive tool for performing combinatorial testing is testcover.com where factors, values, and constraints are simply written in the editor, and test configurations are generated. This tool has an extremely fast and efficient algorithm and can generate about 15 test cases in 1 second. Another advantage is the tool’s easy generator requests where we just have to write the factors and values in new lines, that’s it! Testcover.com also offers the use of functions to add constraints. This tool is a good option for software engineers and testers.
The following things should be noted for using this tool:
- First, all factors are written
- Values for a factor are written in the same line separated by spaces
- Constraints are written at the end using the ‘with’ keyword and parenthesis

5. AnkrPt Pairwise
This simple but powerful tool not only generates tests using the pairwise technique but also can add required tests, negative values, and complex constraints. It is a JAVA-based and completely free tool with GUI which makes it even easier to use for anybody.

Combinatorial Testing tools in Software Testing
Combinatorial testing is a testing technique in which multiple combinations of the input parameters are used to perform testing of the software product.

The aim is to ensure that the product is bug-free and can handle different combinations or cases of the input configuration. One of the most commonly used combinatorial testing methods is the pairwise testing technique which involves testing all pairs of input variable values.
