How to write conditional step with boolean parameter in jenkins scripted pipeline job?

This condition in my script always gets evaluated as true and prints "Yes equal - running the stage" 

stage('test cond'){  
    if(env.BUILD_TESTING2 == true){  
        echo "Yes equal - running the stage"
    } else {
        echo "Not equal - skipping the stage"
    }
}

Even if I start the build by setting env.BUILD_TESTING2 = false it still enters the condition and prints "Yes equal - running the stage".

I also tried this syntax: 

stage('test cond'){  
    if(env.BUILD_TESTING2){  
        echo "Yes equal - running the stage"
    } else {
        echo "Not equal - skipping the stage"
    }
}

But it also still always gets evaluated as true.

How can I write a conditional step with boolean parameter in Jenkins scripted pipeline ?

If you're using booleanParam, the cleanest way that I know is to use when directive with expression.

stage('test cond') {
     when { expression { return params.BUILD_TESTING2 } }
     steps {
        sh 'echo "running the stage"'
    }
}

Better reference parameters by params instead of env, this way they have the correct object type. So use:

stage('test cond') {
    if(params.BUILD_TESTING2) {
        echo "Yes equal - running the stage"
    } else {
        echo "Not equal - skipping the stage"
    }
}

You need to convert this environment variable (of type string) to boolean using toBoolean() function:

stage('test cond'){  
    if(env.BUILD_TESTING2.toBoolean()){  
        echo "Yes equal - running the stage"
    } else {
        echo "Not equal - skipping the stage"
    }
}
