Pairwiser

Library for generate test cases based by pairwise theory

Base theory: All-pairs_testing Base algorithm: barbie.uta.edu

With some modifications

Example

We have system with 10 parameters. As example REST API with input json.

Code example

Map<String, List<Object>> params = new HashMap<>();

for (int i = 0; i < 10; i++) {
	for (int j = 0; j < 10 * Math.random(); j++) {
		params.computeIfAbsent("P" + i, k -> new ArrayList<>()).add("p"+i+"v"+j);
	}
}

PairwiseGenerator<String, Object> gen = new PairwiseGenerator<>(params);
gen.stream().forEach(test -> {
	log.info("Test: {}", test);
});

Type Object used only as example, types of parameters can be any

Maven dependency

<dependency>
  <groupId>com.anyqn.lib</groupId>
  <artifactId>pairwiser</artifactId>
  <version>0.1.21</version>
</dependency>

List of parameters and possible values

  • P0=[p0v0, p0v1, p0v2],
  • P1=[p1v0, p1v1, p1v2, p1v3],
  • P2=[p2v0, p2v1, p2v2, p2v3, p2v4, p2v5],
  • P3=[p3v0, p3v1, p3v2],
  • P4=[p4v0],
  • P5=[p5v0, p5v1, p5v2, p5v3, p5v4, p5v5],
  • P6=[p6v0, p6v1, p6v2, p6v3, p6v4],
  • P7=[p7v0, p7v1],
  • P8=[p8v0, p8v1, p8v2, p8v3, p8v4],
  • P9=[p9v0, p9v1, p9v2]

Micro explain

Bruteforce test cases count is 3 * 4 * 6 * 3 * 1 * 6 * 5 * 2 * 5 * 3 = 194400 Pairwise test cases count = 41

This test cases covered test system by rule "All pairs of params need to add at least once to tests"

Final cases:

  • [p0v0, p1v0, p2v0, p3v0, p4v0, p5v0, p6v0, p7v0, p8v0, p9v0]
