Not able to run the test

[James L.]

It's interesting to test Scala code and my next step will be creating a simple suite for testing web browser with ScalaTest and Selenium, I was not able to run the test below?

import org.scalatest.FlatSpec

import org.openqa.selenium.By

import org.openqa.selenium.WebDriver

import org.openqa.selenium.WebElement

import org.openqa.selenium.htmlunit.HtmlUnitDriver

class GoogleSearch extends FlatSpec {

    val driver = new HtmlUnitDriver

    driver.get("http://www.google.com")

    "Google" should "have the proper title" in {

      assert(driver.getTitle() === "Google")

    }

  }

Using Selenium standalone Jar

C:\Users\james\Desktop>scala -classpath scalatestm4.jar;selenium.jar GoogleSearch

Exception in thread "main" java.lang.RuntimeException: Cannot figure out how to run target: GoogleSearch

Hi James,

I don't see anything wrong with your test class, so perhaps the
problem is in how you are attempting to run it. How are you trying to
run it?

Also, you may be interested in trying ScalaTest's Selenium DSL instead
of using Selenium directly:

I see, I have difficulty doing the test from your tutorial too?

Am I doing the import correctly?

import org.scalatest._

import org.openqa.selenium._

import org.openqa.selenium.WebDriver

import org.openqa.selenium.WebElement

import org.openqa.selenium.htmlunit.HtmlUnitDriver

class BlogSpec extends FlatSpec with ShouldMatchers with WebBrowser {

  implicit val webDriver: WebDriver = new HtmlUnitDriver

  "The blog app home page" should "have the correct title" in {

    go to (host + "index.html")

    title should be ("Awesome Blog")

  }

}

When compiled, it throws:

C:\Users\yanli\Desktop>scalac -classpath scalatestm4.jar;selenium.jar s.scala

s.scala:7: error: not found: type WebBrowser

class BlogSpec extends FlatSpec with ShouldMatchers with WebBrowser {

                                                         ^

s.scala:12: error: not found: value go

    go to (host + "index.html")

    ^

two errors found

Hi James,

You'll need to import WebBrowser from the org.scalatest.selenium
package, like this:

import org.scalatest.selenium.WebBrowser

Great, was able to run REPL and the output does not display?

C:\Users\yanli\Desktop>scala -classpath selenium.jar;scalatestm4.jar s.scala

C:\Users\yanli\Desktop>scala -classpath selenium.jar;scalatestm4.jar;. s.scala

And this would generate an error, BlogSpec.class has been generated, I have no idea what to troubleshoot from here.

C:\Users\yanli\Desktop>scala -classpath selenium.jar;scalatestm4.jar;. BlogSpec

java.lang.NoSuchMethodException: BlogSpec.main([Ljava.lang.String;)

Oh, I got the idea how to run the tests. Thank it works!

C:\Users\yanli\Desktop>scala -classpath selenium.jar;scalatestm4.jar;. org.scalatest.tools.Runner -p BlogSpec

[Bill Venners]

Hi James,

Great. FYI, an even simpler way to run just one suite is:

scala -cp selenium.jar;scalatestm4.jar;. org.scalatest.run BlogSpec
