运行 ant 构建.xml传递"环境 url"参数

Question

我对Ant和编程都是新手。

我做了什么:

我写了一个测试在Java中使用HtmlUnit。我可以使用ant构建来执行我的测试。它工作得很好。我也能够在Jenkins中执行我的ant脚本。

我的问题:

我希望能够在开发，阶段和生产环境中运行我的测试，而无需更改代码。我可以通过这些环境的"URL"作为我的蚂蚁构建的一部分，或者有另一种方法来做到这一点?

我的代码现在看起来是这样的:

配置类:

package com.environments;
import java.io.FileInputStream;
import java.io.IOException;
import java.io.InputStream;
import java.util.Properties;
public class Configuration {
public static String getUrl(String environment) throws IOException {
    Properties prop = new Properties();
    InputStream input = null;
    input = new FileInputStream("configuration/environment.properties");
    prop.load(input);
    String url = prop.getProperty(environment);
    return url;
}

public static String setEnvironment(String url) throws Exception {
    switch (url) {
        case "DEV": url = Configuration.getUrl("DEV"); break; 
        case "STAGE": url = Configuration.getUrl("STAGE"); break; 
        case "LIVE": url = Configuration.getUrl("LIVE"); break;         
    }
    return url;
}
}

测试类:

package com.course_landingpage;
import static com.thoughtworks.twist.core.execution.TwistVerification.verifyEquals;
import org.springframework.beans.factory.annotation.Autowired;
import com.environments.Configuration;
import com.gargoylesoftware.htmlunit.WebClient;
import com.gargoylesoftware.htmlunit.html.DomElement;
import com.gargoylesoftware.htmlunit.html.HtmlAnchor;
import com.gargoylesoftware.htmlunit.html.HtmlPage;
import com.thoughtworks.twist.core.execution.TwistScenarioDataStore;
import com.ui.pagetitles.PageTitles;
public class LandingPageCarouselTest {
public static String url;
@Autowired
private TwistScenarioDataStore scenarioStore;
public LandingPageCarouselTest() throws Exception {         
    url = Configuration.setEnvironment("DEV");
}

// Tests for the landing page carousel
public void verifyCarouselDisplayedWithCourseInformation() throws Exception {
    final WebClient webClient = new WebClient();
    final HtmlPage page = webClient.getPage(url + "/home.html");
    verifyEquals("Incorrect page title", PageTitles.CPD_LANDING_PAGE, page.getTitleText());
    //Click the Discover More button in the carousel 
    final HtmlAnchor anchor = page.getAnchorByText("DISCOVER MORE");
    anchor.click();
    // Click right arrow to view next course in carousel 
    final HtmlAnchor rightArrow = page.getAnchorByText(">");
    rightArrow.click();
    // Click left arrow to view previous course in carousel 
    final HtmlAnchor leftArrow = page.getAnchorByText("<");
    leftArrow.click();
    // Check the course title is correct in the carousel 
    DomElement element = page.getFirstByXPath("/html/body/section/article/ul/li/div/h2");
    final String course1Title = element.getTextContent();
    verifyEquals("Course text is incorrect", course1Title, Configuration.getCourseTitleInCarousel());
    webClient.closeAllWindows();
}

如您所见，当前当我想在不同的环境中运行测试时，我在测试类的构造函数中设置了环境。当前设置为"DEV"。但我可以将其设置为"STAGE"或"LIVE"，以便在其他环境中进行测试。

如果您正在使用java Ant任务执行Java测试类，您可以通过sysproperty嵌套元素将环境URL作为系统属性传递:

<java dir="${testdir}" classname="MainClass">
   <sysproperty key="env.url" value="${env.url}"></sysproperty>
   ...
</java>

你可以像这样在构造函数中访问system属性的值:

url = Configuration.setEnvironment(System.getProperty("env.url"));

${env.url} Ant属性可以从环境中存在的一些配置文件中获取，如另一个用户在他的评论中提到的，或者当您想要运行它时，它可以显式传递给您的Ant构建文件:ant -f build.xml -Denv.url=DEV
