We can use the @Ignore and @IgnoreRest annotation in our Spock specifications to not run the annotated specifications or features. With the @IgnoreIf annotation we can specify a condition that needs to evaluate to true to not run the feature or specification. The argument of the annotation is a closure. Inside the closure we can access three extra variables: properties (Java system properties), env (environment variables) and javaVersion.

In the following Spock specification we have a couple of features. Each feature has the @IgnoreIf annotation with different checks. We can use the extra variables, but we can also invoke our own methods in the closure argument for the annotation:

package com.mrhaki.spock

import spock.lang.*

class SampleRequiresSpec extends Specification {

    private static boolean isOsWindows() {
        System.properties['os.name'] == 'windows'
    }

    @IgnoreIf({ Boolean.valueOf(properties['spock.ignore.longRunning']) })
    def "run spec if Java system property 'spock.ignore.longRunning' is not set or false"() {
        expect:
        true
    }

    @IgnoreIf({ Boolean.valueOf(env['SPOCK_IGNORE_LONG_RUNNING']) })
    def "run spec if environment variable 'SPOCK_IGNORE_LONG_RUNNING' is not set or false"() {
        expect:
        true
    }

    @IgnoreIf({ javaVersion < 1.7 })
    def "run spec if run in Java 1.7 or higher"() {
        expect:
        true
    }

    @IgnoreIf({ javaVersion != 1.7 })
    def "run spec if run in Java 1.7"() {
        expect:
        true
    }

    @IgnoreIf({ isOsWindows() })
    def "run only if run on non-windows operating system"() {
        expect:
        true
    }

}

When we run our specification with Java 1.8 and do not set the Java system property spock.ignore.longRunning or we set the value to false and we do not set the environment variable SPOCK_IGNORE_LONG_RUNNING or give it the value false we can see that some features are ignored:

Now we run on Java 1.7, Windows operating system and set the Java system property spock.ignore.longRunning with the value true and the environment variable SPOCK_IGNORE_LONG_RUNNING with the value true. The resulting report shows the specifications that are ignored and those that are executed:
