Passing parameters to NUnit test via CLI using params

In this post we will discuss yet another useful feature introduced in NUnit 3.x where we can pass a parameter to NUnit test class of C# from Command Line Interface (CLI) using a new feature called –params

Passing parameters

Starting NUnit 3.x, there is an most awaited option introduced for Nunit-console runner, which is passing parameters to test method(s) via CLI using –params

What’s the use case of this?

Consider a scenario something like this, Lets say we have to test application with multiple browsers and we somehow have to parameterize the BrowserType like Firefox,Chrome,IE

Then, we can do it via CLI and pass the parameter to the whole framework to run test based on the parameter (browser type) that we passed.

Here is the complete modified code

FindInSet an best way to verify Collection with Specflow Table

In this post we will discuss about working with FindInSet method of Specflow 2.1 (earlier versions don’t have this method).

FindInSet of Specflow v2.1

With Specflow v2.1, we now have a very handy method to verify an Specflow Table against an collection, which comes very handy while working with large set of data collection and verifying the same against an feature file specflow table something like this

Parallel execution with Specflow 2.0 + NUnit + Selenium

In the last post we discussed how to work with Specflow 2.0 parallel execution, in this post we will discuss how to run Multiple tests in parallel in multiple browser same time using Specflow + NUnit + Selenium.

Problem with Selenium WebDriver object while running Specflow test in Parallel

Since we will be using selenium webdriver object in many Specflow step definitions and while running tests in parallel, we will encounter NullReferenceException , in order to resolve the problem, we need to use two important techniques

  • Context injection (dependency injection)
  • IOC Container

IOC Container

  • In software engineering, inversion of control (IoC) is a design principle in which custom-written portions of a computer program receive the flow of control from a generic framework.
  • A software architecture with this design inverts control as compared to traditional procedural programming: in traditional programming, the custom code that expresses the purpose of the program calls into reusable libraries to take care of generic tasks, but with inversion of control, it is the framework that calls into the custom, or task-specific, code.

-Source : Wikipedia

So how code looks like for IOC Container?

Running Specflow test in Parallel using Specflow 2.0 and NUnit 3.x

In this post we will discuss one of the cool new feature introduced by Specflow 2.0, which is Parallel execution support out-of-box along with NUnit 3.x.

Does NUnit 3.x support parallel execution?

Yes it does, NUnit parallel execution support is discussed in greater details in Selenium automation with C# video series of ExecuteAutomation youtube channel

Parallel execution consideration

In order to achieve parallel test execution, there are some important consideration needed to be taken care before you ensure your test runs properly

Parallel execution with memory isolation (AppDomain)

  • Ensure your test code executing the application is not depends on static states (e.g. external cache, databases etc), if so then
  • This can be achieved by isolating test into AppDomain, this ensures that every test execution thread is hosted in a separate AppDomain and that each thread’s memory

Parallel execution without memory isolation (AppDomain)

  • If your tests do not depend on any static states (ie. do not store any test-specific information in static fields), you can run the tests in parallel without AppDomain isolation

What’s the code change in existing specflow code ?

It’s fairly very simple, just one line of additional change in AssemblyInfo.cs file and you are good to go and the change is this

PicklesUI an easy option to generate Specflow documentation

In the last post we discussed how to generate Specflow scenario documentation using Pickles with Visual studio package manager console via command line interface.

In this post we will discuss how to generate Specflow documentation using PicklesUI, which has an easy to use GUI as opposed to command

Pickles an living documentation for Specflow feature file

In this post we will discuss about Pickles, an opensource tool for generating documentation for Specflow feature files.

What is Pickles

Pickles is an open source living documentation generator that works on feature files written in the Gherkin language, popularized in tools like Cucumber and SpecFlow.

Pickles can be incorporated into your build process to produce living documentation in a format that is more accessible to your clients. Gherkin language files are written in plain text and stored in your source folder

Pickles supported output formats

Pickles can produce output in different formats:

ØStatic HTML: a set of HTML files with minimal JavaScript

ØDynamic HTML: a JavaScript-rich single page app with integrated search

ØWord: Microsoft Word

ØExcel: Microsoft Excel

ØJSON: a custom JSON format

Installing Pickles via Nuget

The command to install Pickles from Nuget of Visual studio IDE is this
