Nunit 3: Can tests in one class run in parallel with Parallelizable attribute? - nunit-3.0

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?

Is there any possible way of running testng test groups in #factory method annotation?

I have my framework on #factory annotation. The test suite initializes the factory class which in turn runs the #test annotated methods.
I need to run specific tests groups only which can be initialized at suite level.
or if there is any way of running a specific factory method from the complete suite

How to disable a parallel run for a specific SpecFlow scenario?

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.

How to use TestNg in Selenium WebDriver?

How to use TestNg in Selenium WebDriver? Explain me what is the usage of that.
I am new Learner in Selenium WebDriver
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).

Difference between Testng class and normal Java class

What is the difference between Testng Class and a normal Java class. While creating an Automation suite in Selenium should we use Testng class or normal java class in Eclipse.
TestNg is not language it's a testing framework. See this
TestNG is a testing framework inspired from JUnit and NUnit
This is a framework to handle different kind of testing such as unit,end to end, functional and so more. It uses Java and provide supports and annotations to drive testings. That's it!
A TestNg class is a Java class, but a Java class does not have to be a TestNg class.
The following is from the TestNg documentation and gives an understanding what you can do with the TestNg class:
This class is the main entry point for running tests in the TestNG
framework. Users can create their own TestNG object and invoke it in
many different ways:
On an existing testng.xml
On a synthetic testng.xml, created entirely from Java
By directly setting the test classes
You can also define which groups to include or exclude, assign
parameters, etc...
From: http://testng.org/javadoc/org/testng/TestNG.html
TestNg is basically is a set of code written in Java that allows you to create tests.
A TestNG class is a Java class that contains a method annotated by this class: org.testng.annotations.Test;
Testng Class and a normal Java class
TestNG Class: TestNg class is nothing but any normal class with TestNG annotation and Annotation is a tag that represents the metadata which gives the addition information about class, methods and interface.
To know more about annotation Please refer this https://docs.oracle.com/javase/tutorial/java/annotations/
While creating Automation suite we use either JUNIT or TestNG. JUNIT or TestNG are testing framework. They have their own set of libraries and annotations which is useful to run our automation suite. JUNIT or TestNG makes easy to run automation suite or generate reports of build run. They provide the feature to setup or cleanup activity using Before and After annotation which is require in almost every autoamtion suite.
TestNG also provide us flexibility to execute our automation script based on our requirement like we can group of test cases, we can include or exclude methods, parallel execution of test methods and many more.
Please refer this to know more about TestNG.

I hope this will help.

junit suite tests, in phases: All #Before, then all #Test, then all #After

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(){}
