Not able to read json test data file into my stepDef. When I try to execute this in maven I am getting below error message.

My Scenario Scenario Outline: JSON Keyword Example Given I am on github login page #And I enter "" and "" And I enter usernames and passwords

Examples: {'datafile':'./src/main/resources/data/testData.json'}

My testData.json

[
  { "username" : "jsonuser1" , "password":"jsonpass1" , "isvalid":"false" }
]

StepDefinition

@And("^I enter usernames and passwords$")
public void iEnterUsernamesAndPasswords(Map<Object, Object> data) {
    System.out.println("*************************"+ data.get("username") + data.get("password"));
    
}

Error Msg:

For any step that required arguments, you need to specify argument placeholder when defining step and need to provide value the time of call. In your case try to update step definition as below:

@And("^I enter usernames and passwords \"([^\"]*)\"$")
public void iEnterUsernamesAndPasswords(Map<Object, Object> data) {
System.out.println("*************************"+ data.get("username") + data.get("password"));
}

Pass the data at the time of step call,

    Given I am on github login page
    And I enter usernames and passwords "${args[0]}"
