Pairwise is open-source library for the generating minimal set of test combinations. The project is implemented In-Parameter-Order (IPO) a strategy for generate test cases.
mvn clean installNow you can use library in your projects, include in pom.xml the following dependency
<dependency>
<groupId>ua.edu.lp.asu</groupId>
<artifactId>pairwise</artifactId>
<version>0.3.2-SNAPSHOT</version>
</dependency>Example using generating test cases
Pairwise pairwise = new Pairwise.Builder()
.withParameters(Arrays.asList(
new Parameter<>("Platform", Platform.x86, Platform.ia64, Platform.amd64),
new Parameter<>("CPUs", "Single", "Dual", "Quad"),
new Parameter<>("RAM", "128MB", "1GB", "4GB", "64GB"),
new Parameter<>("HDD", Type.SCSI, Type.IDE),
new Parameter<>("Operating system", new NT4(), new Win2K(), new WinXP(), new Win2K3()),
new Parameter<>("Internet Explorer", 4.0, 5.0, 5.5, 6.0),
new Parameter<>("Application", new SQLServer(), new Exchange(), new Office())))
.build();
for (Case o : pairwise) {
// TODO: write your code here
}This is output of generating test cases. Each of the following lines represents one generated test case.
No. | Platform | CPUs | RAM | HDD | Operating system | Internet Explorer | Application
----+----------+--------+-------+------+------------------+-------------------+-------------
0 | amd64 | Quad | 128MB | IDE | NT4@5910e440 | 4.0 | SQLServer
1 | x86 | Single | 1GB | SCSI | NT4@5910e440 | 5.0 | Office
... | ... | ... | ... | ... | ... | ... | ...
17 | ia64 | Dual | 4GB | SCSI | WinXP@533ddba | 5.5 | Exchange
Also, you can use pairwise testing with TestNG as @DataProvider
@DataProvider
public Object[][] source() {
return new Pairwise.Builder()
.withParameter(new Parameter<>("Type", "Primary", "Logical", "Single", "Span", "Stripe"))
.withParameter(new Parameter<>("Size", 10, 100, 500, 1000, 5000, 10000, 40000))
.withParameter(new Parameter<>("File system", Fs.FAT, Fs.FAT32, Fs.NTFS))
.withParameter(new Parameter<>("Cluster size", 512, 1024, 2048, 4096, 8192, 16384, 32768, 65536))
.withParameter(new Parameter<>("Compression", true, false))
.build()
.toTestNG();
}
@Test(dataProvider = "source")
public void test(String type, Integer size, Fs fs, Integer cluster, Boolean compression) {
// TODO: write your code here
}or running parameterized test in JUnit 4
@Parameterized.Parameters
public static Collection<Object[]> source() {
return new Pairwise.Builder()
.withParameter(new Parameter<>("Type", Type.CD, Type.DVD))
.withParameter(new Parameter<>("Recording Speed", 2, 4, 8, 16, 24, 36, 52))
.withParameter(new Parameter<>("File System", Fs.ISO, Fs.UDF, Fs.HFS, Fs.ISO9660))
.withParameter(new Parameter<>("Capacity", new Capacity("700Mb"), new Capacity("4.7Gb")))
.build()
.toJUnit();
}
