How to rerun the failed scenarios using Cucumber?

Question

I'm using Cucumber for my tests. How do I rerun only the failed tests?

Answer 1

Run Cucumber with rerun formatter:

cucumber -f rerun --out rerun.txt 

It will output locations of all failed scenarios to this file.

Then you can rerun them by using

cucumber @rerun.txt 

Answer 2

Here is my simple and neat solution.

Step 1: Write your cucumber java file as mentioned below with rerun:target/rerun.txt. Cucumber writes the failed scenarios line numbers in rerun.txt as shown below.

features/MyScenaios.feature:25 features/MyScenaios.feature:45 

Later we can use this file in Step 2. Name this file as MyScenarioTests.java. This is your main file to run your tagged scenarios. If your scenarios has failed test cases, MyScenarioTests.java will write/mark them rerun.txt under target directory.

@RunWith(Cucumber.class) @CucumberOptions(     monochrome = true,     features = "classpath:features",     plugin = {"pretty", "html:target/cucumber-reports",               "json:target/cucumber.json",               "rerun:target/rerun.txt"} //Creates a text file with failed scenarios               ,tags = "@mytag"            ) public class MyScenarioTests   {  } 

Step 2: Create another scenario file as shown below. Let's say this as FailedScenarios.java. Whenever you notice any failed scenario run this file. This file will use target/rerun.txt as an input for running the scenarios.

@RunWith(Cucumber.class) @CucumberOptions(     monochrome = true,     features = "@target/rerun.txt", //Cucumber picks the failed scenarios from this file      format = {"pretty", "html:target/site/cucumber-pretty",             "json:target/cucumber.json"}   ) public class FailedScenarios {  } 

Everytime if you notice any failed scenarios run the file in Step 2
