Is it possible to exclude a specflow scenario from parallel run?
I set up parallel run for all the assembly by doing this:
[assembly: Parallelize(Workers = 10, Scope = ExecutionScope.ClassLevel)]
in AssemblyInfo.cs file.
But now I need to exclude one specific scenario from parallel run. How can I do it?
One way to solve this is to use the NonParallelizable Attribute, provided by NUnit.
Example:
namespace Tests
{
[SetUpFixture]
public class TestsSetUpFixture
{
//setup the tests
}
[TestFixture]
[NonParallelizable]
public class TestFixture1
{
[Test]
public void TestFixture1_Test()
{
//do stuff in your test
}
}
}
NUnit provides this documentation:
This attribute is used to indicate that the test on which it appears
may not be run in parallel with any other tests. The attribute takes
no arguments and may be used at the assembly, class or method level.
When used at the assembly level, its only effect is that execution
begins on the non-parallel queue. Test suites, fixtures and test cases
will continue to run on the same thread unless a fixture or method is
marked with the Parallelizable Attribute.
When used on a test fixture or method, that test will be queued on the
non-parallel queue and will not run while other tests marked as
Parallelizable are being run.
Hope this helps.

I am supposed to migrate on Cucumber. I do have project framework with Selenium, TestNG with Data Driven Framework, Maven. I am exploring Cucumber feasibility with TestNG annotation.
My question is, How we can create connection between #Test method and Step definition of cucumber. Let's example our code is written in #BeforeClass, #Test, #AfterClass method. So how we can migrate with Step definition.
Feature File :
Feature: Is it Friday yet?
Everybody wants to know when it's Friday
Scenario: Sunday isn't Friday
Given today is Sunday
When I ask whether it's Friday yet
Step Definition:
#Given("^today is Sunday$")
public void today_is_Sunday() {
// Write code here that turns the phrase above into concrete actions
System.out.println("this is demo1");
}
#When("^I ask whether it's Friday yet$")
public void i_ask_whether_is_s_Friday_yet() {
// Write code here that turns the phrase above into concrete actions
System.out.println("this is demo2");
}
Class Exection:
#CucumberOptions(features = "cfeature/firstDemo.feature", glue = { "mytest/Stepd" })
public class demo01 extends AbstractTestNGCucumberTests {
private TestNGCucumberRunner tcr;
#BeforeClass(alwaysRun = true)
public void beforeClass() throws Exception {
tcr = new TestNGCucumberRunner(this.getClass());
}
#Test(groups="cucumber", description="Runs CucumberFeature")
public void testdemo() {
System.out.println("Hello");
}
#AfterClass(alwaysRun = true)
public void afterClass() {
tcr.finish();
}
}
Console:
Hello
[33mUndefined scenarios:[0m
[33mcfeature/firstDemo.feature:4 [0m# Sunday isn't Friday
1 Scenarios ([33m1 undefined[0m)
5 Steps ([33m5 undefined[0m)

You can implement missing steps with the snippets below:
As of now, #Test annotation is calling. But, How to replace it with Step Definition. Please assist.
Not sure what the confusion here. Here's how you can relate TestNG and cucumber terminologies.
<test> tag in TestNG can be visualized as a feature file in cucumber.
#Test method in TestNG can be visualized as a scenario in cucumber.
A Step definition in cucumber has nothing directly equivalent to in TestNG because, its part of a scenario. But for the sake of understanding you can visualize it as one line of code doing a logical operation in TestNG.
The default implementation of AbstractTestNGCucumberTests is as below:
It contains a data provider internally which provides one feature file at a time.
It contains a #Test method which is bound to the above mentioned data provider, which retrieves all the scenarios in the feature file and then runs them one after the other.
You can build your own variant of AbstractTestNGCucumberTests to do various different things (such as support concurrent scenario execution which is currently not available in Cucumber JVM bindings).
As an example you can take a look at Cucumber-roadrunner library that I built which uses the above concept to support parallel scenario execution and also provides thread safe reports.
With respect to the error you are facing viz., You can implement missing steps with the snippets below: is basically because cucumber jvm bindings perhaps isn't able to bind your feature file with a glue code (which is what you are providing via the #CucumberOptions annotation). You should perhaps take a closer look at the cucumber jvm bindings documentation to understand how to provide the correct values.
You can also take a look to gherkin with QAF which is pure TestNG implementation for gherkin. It is using TestNG (NOT cucumber runner) and provides you all the features of testNG including parallel execution, listeners, grouping, priority etc...
Each scenario converted as TestNG test and you can run scenarios as parallel. Furthermore you can also use inbuilt or custom data-providers while authoring BDD. No need additional runner just configure as usual using appropriate factory class for the BDD syntax you are using.
I am using
[TestFixture]
[Parallelizable(ParallelScope.Children)]
public class MyTests
{
}
There are 5 tests within this class.
I am using NUnit 3 Test Adapter.
I also have the below in my AssemblyInfo of test project:
[assembly: Parallelizable(ParallelScope.Fixtures)]
In the test window I notice that multiple classes are running in parallel. However, the tests within each class are run synchronously.
How can I achieve parallelism within each class?
How to use TestNg in Selenium WebDriver? Explain me what is the usage of that.

Hi TestNG can be defined as
1.TestNG is a testing framework designed to simplify a broad range of testing needs, from unit testing (testing a class in isolation of the others) to integration testing (testing entire systems made of several classes, several packages and even several external frameworks, such as application servers).
2.For official TestNG documentation Please Click Here
Before you can use TestNG with selenium you have to install it first.Talking in consideration that you are working with eclipse (any version)
1.There are various ways to install TestNG either follow this or this or simply go to Help/Eclipse MarketPlace. under Find type Test NG and click on the install
now how to use Test NG in eclipse with selenium
#BeforeTest
public void TearUP(){
// preconditions for sample test
// like browser start with specific URL
}
#Test
public void SampleTest(){
// code for the main test case goes inside
}
#AfterTest
public void TearDown1(){
// thing to done after test is run
// like memory realese
// browser close
}
Some information for above code
TestNG have various annotations for more info on annotation go to the above link
#BeforeSuite: The annotated method will be run before all tests in this suite have run.
#AfterSuite: The annotated method will be run after all tests in this suite have run.
#BeforeTest: The annotated method will be run before any test method belonging to the classes inside the <test> tag is run.
#AfterTest: The annotated method will be run after all the test methods belonging to the classes inside the <test> tag have run.
#BeforeGroups: The list of groups that this configuration method will run before. This method is guaranteed to run shortly before the first test method that belongs to any of these groups is invoked.
#AfterGroups: The list of groups that this configuration method will run after. This method is guaranteed to run shortly after the last test method that belongs to any of these groups is invoked.
#BeforeClass: The annotated method will be run before the first test method in the current class is invoked.
#AfterClass: The annotated method will be run after all the test methods in the current class have been run.
#BeforeMethod: The annotated method will be run before each test method.
#AfterMethod: The annotated method will be run after each test method.
One of the primary usage of selenium is to test ui functionality, and as a testing framework testNg has many techniques to run and report the tests and can be leveraged for ui testing with selenium. One of the tools effectively use this is selion (https://github.com/paypal/selion).
I have a bit of a special situation. Basically I have a unit test, annotated with #Test, and inside that test I need to execute a Cucumber JVM test class.
Why? Long story. Something to do with classloaders and RoboGuice, it's not very important but it does impose limits on what I can and cannot do.
Here's the test method:
#Test
public void runCucumberFeature() throws Exception {
Cucumber cucumber = new Cucumber(MyCucumberTest.class);
cucumber.run(new RunNotifier());
}
MyCucumberTest is a class I have created, and annotated like this:
//#RunWith(Cucumber.class)
#Cucumber.Options(format = {"pretty", "html:target/cucumber"}, strict=true)
public class MyCucumberTest {
// Empty, as required by Cucumber JVM
}
Why have I commented out the #RunWith annotation? Because if I don't, the Cucumber test runner will pick up the test and run it, which I don't want because I am running the test manually.
The problem is that the above doesn't work. It looks like Cucumber is finding the feature files, it is verifying that MyCucumberTest contains the #Givens etc, it even prints out the test as if it was running it.
But it doesn't. No code is executing inside the #Given, #When and #Then methods. I'm not sure why this is, but I have a vague idea that the Cucumber JVM test runner doesn't want to execute the code because the class isn't annotated with #RunWith.
Can anyone help?
I can't provide the solution you're looking for, but....
... have you considered tagging the test that you want to run manually (e.g. with #Manual)?
Then you could uncomment your #RunWith annototation and exclude the manual test by adding --tags ~#Manual to your Cucumber-JVM invocation.
In your manual JUnit invocation you could add --tags #Manual
I'd like a junit runner that executes all #Before methods, then all #Test methods, then all #After methods.
This is how my System-Tests work. The #Before methods are run, to setup the test data and scenarios. The application is started. Then the #Test methods are run with the application running in the background. Those #Test methods can change data or respond to the application. Then the framework waits for the application to finish up. Afterward, the #After methods are run to verify the test results.
I already use junit annotations, assertion methods, and other various bits. But I just can't figure out how to use junits runners to execute test methods in this way. I couldn't make heads nor tails of the "Computer" interface in junit 4.8, or figure out how to apply Rules to this.
This isn't what JUnit does. JUnit has a design philosophy that emphasizes independent unit tests. As such, it isn't a natural framework for system tests. What you want to do fits nicely into TestNG (which as a design goal tries to straddle both unit and system tests).
In JUnit the #Before and #After are run before and after each test. You can shoehorn this kind of thing into JUnit using a Suite, which references all of your tests and is responsible for all setup and teardown, so the Suite's #BeforeClass and #AfterClass methods get run before and after the suite, which if you organize it correctly could be all of your system tests.
There are lot of organizational challenges in the code when it gets large with the JUnit approach, so I would suggest you consider and alternative framework if this is the bulk of what you want to do.
I think you can solve this by making only one actual test method, that just calls are your actual tests, which you do not declare as ssuch.
Kinda like:
#Before
public void beforeTest(){}
#After
public void afterTest(){}
#Test
public void test(){
test1();
test2();
test3();
}
public void test1(){}
public void test2(){}
public void test3(){}
