The error message "window is not defined" occurs when the external file 'signalr.min.js' is included

Updates

  • OpenTest --version 1.2.2
  • ChromeDriver 85.0.4183.87

Whenever I attempt to add the necessary external javascript files, it results in the following errors:

Caused by: java.lang.RuntimeException: Failed to evaluate JavaScript code at line number 1. The script content was: 
$include(["signalr.min.js", "signalr.tests.js"]);
...
Caused by: java.lang.RuntimeException: Failed to run script file signalr.min.js
...
Caused by: javax.script.ScriptException: ReferenceError: "window" is not defined in <eval> at line number 1

I have consulted the documentation at:

Despite trying various combinations, none of them seem to be effective. It appears that I am overlooking something :(

My actor.yml file is set up with the chrome web-driver configured as follows:

# Selenium options
selenium:
    # seleniumServerUrl: http://127.0.0.1:9515
    desiredCapabilities:
        browserName: chrome
        chromeOptions:
            args: [ --start-maximized ]
    chromeDriverExePath: C:/Webdrivers/chromedriver.exe

Answer №1

After numerous trials and errors, I finally found a solution that works. I couldn't get the script-includes to work in OpenTest, probably because of issues when the browser is not yet opened and the window object is undefined. This means scripts that rely on the DOM won't work...

What I ended up doing was creating a local HTML page that executes some JavaScript, and then calling that page from the OpenTest YAML file with some validations. Here is an example of how I approached this:

description: My Test
actors:
  - actor: ACTOR1
    segments:
      - segment: 1
        actions:
          - description: Initialize Browser
            action: org.getopentest.selenium.NavigateTo
            args:
              url: $data("config").someExternalUrlIsAlive
              
          - description: Get Test Page File-Path
            script: |
              var File = Java.type("java.io.File");
              var URLEncoder = Java.type("java.net.URLEncoder");
              var StandardCharsets = Java.type("java.nio.charset.StandardCharsets");

              var testPage = new File("..\\test-repo\\scripts\\testpage.html");
              var testPageUrl = testPage.getAbsolutePath();

              var argument = $data("config").someProperty;
              var argumentUrlEncoded = URLEncoder.encode(argument, StandardCharsets.UTF_8.toString());

              $sharedData.testpage = testPageUrl + "?arg=" + argumentUrlEncoded;
              $log("The test-page path is " + $sharedData.testpage);

          - description: Navigate to Test Page
            action: org.getopentest.selenium.NavigateTo
            args:
              url: $sharedData.testpage

          - description: Start Test
            action: org.getopentest.selenium.Click
            args:
              locator: { id: btnTest }

          - description: Give the test some time to complete
            script: |
              var Thread = Java.type("java.lang.Thread");
              Thread.sleep(3000); // sleep 3 seconds.

          - description: Read Test Page Result
            action: org.getopentest.selenium.GetElements
            args:
              locator: { id: txtResult }
              $localData:
                resultElements: $output.elements

          - description: Validate the Test Page Results
            script: |
              var txtResult = $localData.resultElements[0];
              var testResult = txtResult.getAttribute("value")

              if (testResult !== "200") {
                $fail(
                  $format(
                    "We expected a valid connection result, but we got: {0}",
                    testResult
                  )
                );
              }
