Olá, estou tentando executar o teste, ele chega a abrir o Firefox mas fecha e logo em seguida estoura o erro:

java.lang.NoSuchMethodError: com.google.common.base.Joiner$MapJoiner.appendTo(Ljava/lang/StringBuilder;Ljava/lang/Iterable;)Ljava/lang/StringBuilder; at com.google.common.net.MediaType.toString(MediaType.java:714) at org.openqa.selenium.remote.http.JsonHttpCommandCodec.encode(JsonHttpCommandCodec.java:222) at org.openqa.selenium.remote.HttpCommandExecutor.execute(HttpCommandExecutor.java:139) at org.openqa.selenium.firefox.internal.NewProfileExtensionConnection.execute(NewProfileExtensionConnection.java:170) at org.openqa.selenium.firefox.FirefoxDriver$LazyCommandExecutor.execute(FirefoxDriver.java:380) at org.openqa.selenium.remote.RemoteWebDriver.execute(RemoteWebDriver.java:620) at org.openqa.selenium.remote.RemoteWebDriver.startSession(RemoteWebDriver.java:247) at org.openqa.selenium.remote.RemoteWebDriver.(RemoteWebDriver.java:129) at org.openqa.selenium.firefox.FirefoxDriver.(FirefoxDriver.java:218) at org.openqa.selenium.firefox.FirefoxDriver.(FirefoxDriver.java:211) at org.openqa.selenium.firefox.FirefoxDriver.(FirefoxDriver.java:207) at org.openqa.selenium.firefox.FirefoxDriver.(FirefoxDriver.java:120) at app.test.selenium.CadastroUsuarioTest.devePersistirUsuario(CadastroUsuarioTest.java:34) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source) at java.lang.reflect.Method.invoke(Unknown Source) at org.junit.runners.model.FrameworkMethod$1.runReflectiveCall(FrameworkMethod.java:45) at org.junit.internal.runners.model.ReflectiveCallable.run(ReflectiveCallable.java:15) at org.junit.runners.model.FrameworkMethod.invokeExplosively(FrameworkMethod.java:42) at org.junit.internal.runners.statements.InvokeMethod.evaluate(InvokeMethod.java:20) at org.junit.internal.runners.statements.RunAfters.evaluate(RunAfters.java:30) at org.junit.runners.ParentRunner.runLeaf(ParentRunner.java:263) at org.junit.runners.BlockJUnit4ClassRunner.runChild(BlockJUnit4ClassRunner.java:68) at org.junit.runners.BlockJUnit4ClassRunner.runChild(BlockJUnit4ClassRunner.java:47) at org.junit.runners.ParentRunner$3.run(ParentRunner.java:231) at org.junit.runners.ParentRunner$1.schedule(ParentRunner.java:60) at org.junit.runners.ParentRunner.runChildren(ParentRunner.java:229) at org.junit.runners.ParentRunner.access$000(ParentRunner.java:50) at org.junit.runners.ParentRunner$2.evaluate(ParentRunner.java:222) at org.junit.runners.ParentRunner.run(ParentRunner.java:300) at org.eclipse.jdt.internal.junit4.runner.JUnit4TestReference.run(JUnit4TestReference.java:86) at org.eclipse.jdt.internal.junit.runner.TestExecution.run(TestExecution.java:38) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.runTests(RemoteTestRunner.java:459) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.runTests(RemoteTestRunner.java:675) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.run(RemoteTestRunner.java:382) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.main(RemoteTestRunner.java:192)

Código é esse:

@Test public void devePersistirUsuario(){ // parte 2 : ação // determino a url a ser aberta pelo browser no teste this.driver = new FirefoxDriver(); this.driver.get("http://localhost:8080/usuario/new");

WebElement usuario = this.driver.findElement(By.name("usuario.nome")); WebElement email = this.driver.findElement(By.name("usuario.email"));

// preencho os campos do formulário usuario.sendKeys("Adriano Xavier"); email.sendKeys("axavier@empresa.com.br");

// realizo o a interação com o botão salvar do formulário WebElement botaoSalvar = this.driver.findElement(By.id("btnSalvar")); botaoSalvar.click();

boolean existeNome = this.driver.getPageSource().contains("Adriano Xavier"); boolean existeEmail = this.driver.getPageSource().contains("axavier@empresa.com.br");

assertThat(existeNome, equalTo(true)); assertThat(existeEmail, equalTo(true)); }
