动态生成GlobalVariable

Question

我曾尝试在https://docs.katalon.com/katalon-studio/docs/create-global-variables-on-the-fly.html中动态创建一个GlobalVariable。

关键字定义是，

public class Helper {

@Keyword
void addGlobalVariable(String name, def value) {
  GroovyShell shell1 = new GroovyShell()
  MetaClass mc = shell1.evaluate("internal.GlobalVariable").metaClass
  String getterName = "get" + name.capitalize()
  mc.'static'."$getterName" = { -> return value }
  mc.'static'."$name" = value
}

脚本代码是，

CustomKeywords.'Helper.addGlobalVariable'('localURL'，'katalon.com') println GlobalVariable.localURL

我收到以下错误

请让我知道如何解决这个问题。谢谢。

您只需在同一执行中创建GlobalVariables即可。换句话说，如果您像这样创建一个GlobalVariable，那么您可以在创建它的测试用例中使用它，或者在执行它的测试套件的下一个测试用例中使用它(显然是执行整个测试套件，而不仅仅是创建GlobalVariable的测试用例)。

实际上，这不是一个永久创建或编辑GlobalVariable的选项。

你能做的，就是创建一个文件并保存在你想要的任何地方，然后在你想要的任何地方恢复信息。

这里有一个示例: TestScript1。

    import java.nio.file.Files
    import java.nio.file.Path
    import java.nio.file.Paths

    import com.kms.katalon.core.configuration.RunConfiguration
    import com.kms.katalon.core.testobject.ConditionType
    import com.kms.katalon.core.testobject.TestObject as 
    import com.kms.katalon.core.webui.keyword.WebUiBuiltInKeywords as WebUI

    // parameters
    def URL = "https://www.google.com/search?q=katalon"
    def testObject = new TestObject().addProperty("xpath", "//div[@id='resultStats']")

    // create directory to locate a temporary file
    Path projectDir = Paths.get(RunConfiguration.getProjectDir())
    Path tmpDir = projectDir.resolve('tmp')
    if (!Files.exists(tmpDir)) {
        Files.createDirectory(tmpDir)
    }

    // Prepare File object 
    File dataFile = tmpDir.resolve('data.txt').toFile()

    // open a web page
    WebUI.openBrowser('')
    WebUI.navigateToUrl(URL)
    WebUI.verifyElementPresent(testObject, 10)

    // retrieve a text labeled "result stats" from the Google Search Result page 
    String value = WebUI.getText(testObject).trim()

    // save the text into a file under <project dir>/tmp directory
    dataFile.text = value

    WebUI.closeBrowser()

TestScript2

    import java.nio.file.Files
    import java.nio.file.Path
    import java.nio.file.Paths

    import com.kms.katalon.core.configuration.RunConfiguration
    import com.kms.katalon.core.testobject.ConditionType
    import com.kms.katalon.core.testobject.TestObject as TestObject
    import com.kms.katalon.core.webui.keyword.WebUiBuiltInKeywords as WebUI

    // parameters
    def URL = "https://www.google.com/search?q=katalon"
    def testObject = new TestObject().addProperty("xpath", ConditionType.EQUALS,         "//div[@id='resultStats']")

    // create directory to locate a temporary file
    Path projectDir = Paths.get(RunConfiguration.getProjectDir())
    Path tmpDir = projectDir.resolve('
    if (!Files.exists(tmpDir)) {
        Files.createDirectory(tmpDir)
    }

    // read the file to retrieve the data prepared by TestScript1
    File dataFile = tmpDir.resolve('data.txt').toFile()
    String previousValue = dataFile.text.trim()

    // open a web page
    WebUI.openBrowser('')
    WebUI.navigateToUrl(URL)
    WebUI.verifyElementPresent(testObject, 10)

    // verify if the same value as the data is displayed in the web page

    //WebUI.verifyTextPresent(value, false)        // this line often fails with no         meaningful diagnostics 

    def currentValue = WebUI.getText(testObject).trim()
    assert currentValue == previousValue

    WebUI.closeBrowser()

我从这里获取了这些信息(我把它粘贴在这里，以防将来URL会被破坏)：

我希望它能有所帮助，尽管我回答得太晚了。
