Gradleを使ってSeleniumベースなテストをサーバー起動を含め自動化しちゃいたい場合のメモ

テストケース (SampleTestCase.java)

package sample.test.integration;

import org.junit.After;
import org.junit.Before;
import org.junit.Test;

import com.thoughtworks.selenium.DefaultSelenium;
import com.thoughtworks.selenium.Selenium;

import static org.junit.Assert.*;

public class SampleTestCase {

    private Selenium selenium;

    @Before
    public void setUp() throws Exception {
        selenium = new DefaultSelenium(
            "localhost",
            4444,
            "*chrome",
            "http://localhost:8081"
        );
        selenium.start();
    }

    @Test
    public void testIndex() {
        selenium.open("/");

        assertEquals("test", selenium.getTitle());
    }

    @After
    public void tearDown() {
        selenium.stop();
    }
}

build.gradle

(ベースは以前作ったSAStrutsのプロジェクトベース)

buildDir = "target"

apply {
    plugin "war"
    plugin "jetty"
    plugin "eclipse"
}

repositories {
    mavenCentral()
    maven {
        url "http://maven.seasar.org/maven2"
    }
}

configurations {
    selenium
}

dependencies {
    compile "org.seasar.sastruts:sa-struts:1.0.4-sp9"
    compile "org.apache.geronimo.specs:geronimo-ejb_3.0_spec:1.0"
    compile "org.apache.geronimo.specs:geronimo-jta_1.1_spec:1.0"
    compile "org.apache.geronimo.specs:geronimo-jpa_3.0_spec:1.0"
    compile "mysql:mysql-connector-java:5.1.21"

    testCompile "org.seleniumhq.selenium:selenium-java:2.28.0"

    selenium "org.seleniumhq.selenium:selenium-server:2.28.0"
}

sourceSets {
    main {
        output.classesDir = "${buildDir}/classes"
        output.resourcesDir = "${buildDir}/classes"
    }

    test {
        output.classesDir = "${buildDir}/test-classes"
        output.resourcesDir = "${buildDir}/test-classes"
    }
}

[jettyRun, jettyRunWar]*.contextPath = ""
[jettyRun, jettyRunWar]*.httpPort = 8081
jettyStop.stopPort = 8081
jettyStop.stopKey = "stopKey"

test {
    // integrationパッケージは通常テストから除外
    exclude "**/integration/**"
}

task integrationTest(type: Test) {
    include "**/integration/**"

    doFirst {
        // integrationTest前にJettyをデーモンモードで起動
        jettyRun.daemon = true
        jettyRun.execute()
    }

    doLast {
        // 終了後にJettyサーバーを停止
        jettyStop.execute()
    }
}

// Selenium ServerをintegrationTest時に起動する
task startSeleniumServer {
    ant.java(
        classname: "org.openqa.selenium.server.SeleniumServer",
        classpath: configurations.selenium.asPath,
        fork: true,
        spawn: true
    )
}

integrationTest.dependsOn startSeleniumServer

eclipse {
    project {
        natures "org.springsource.ide.eclipse.gradle.core.nature"
    }

    classpath.file {
        whenMerged { classpath ->
            classpath.entries.findAll { entry ->
                entry.kind == "output"
            }*.path = "target/classes"
        }
    }
}

gradle integrationTestを行う事でSelenium Server及びJettyサーバーを起動してテストを実行、その後サーバーをシャットダウン(但し、Seleniumサーバーはダウンしない)

な感じでテスト出来る模様。
