Handling multiple assert in Selenium with Assert.multiple of NUnit 3.6

In this post we will discuss how to handle multiple assert in Selenium with Assert.multiple of NUnit 3.6, this is one of the most requested feature of NUnit.

NUnit 3.6

Nunit 3.6 released by Jan 9th 2017 has number of notable improvement and features something like this

  • .NET Standard 1.6 is now supported
  • Adds support for Multiple Assert blocks
  • Added the –params option to NUnitLite
  • Theories now support Nullable enums
  • Improved assert error messages to help differentiate differences in values
  • Added warnings with Warn.If(), Warn.Unless() and Assert.Warn()
  • Enabled Path, File and Directory Asserts/Contraints for .NET Core testing
  • Added NonTestAssemblyAttribute for use by third-party developers to indicate that their assemblies reference the NUnit framework, but do not contain tests

Where is Assert.Multiple helpful ?

Consider a scenario something like this

Lets say we have to test multiple properties of an UI element in Selenium

In Nunit test framework, if the first assert fails (not meeting the condition), then the second assertion will not even takes place and the whole test fails (which we all know)

But using new Assert.Multiple method, the code can be written something like this

Working with Cucumber Hooks to Initialize and Teardown tests

In our last post we discussed working with multiple data using DataTable and Custom classes of DataTable, in this post we will discuss working with cucumber hooks and how helpful it is to initialize and teardown different test artifacts

Cucumber hooks

If you are from Specflow background, you might have noticed there are different types of hooks available like

But unfortunately in cucumber for Java we only have two hooks

  • @After
  • @Before

Limitation in cucumber for Java

In Specflow, you can call hooks for each and every steps, features, scenario, scenario block or whole test run, but its not possible with cucumber for Java

Here is the complete video of the above discussion

Working with multiple data using DataTable in Cucumber for Java

In our last post we discussed getting started with cucumber for Java, in this post we will discuss working with multiple data using DataTable in Cucumber for Java. We have already discussed about working with multiple data in Specflow of C#, which has Table class, but here in Cucumber for Java they have class named DataTable.

Working with multiple data in Cucumber

We might need to supply multiple data instead of hardcoded value passed in steps from feature files, this happens most of the time while working with your project

This can be done using DataTable class available in Cucumber, basically DataTables are of type List<List<String>>

Table in the scenario looks something like this

Setting Selenium grid with Docker compose

In our last post on docker compose, we discussed what docker compose is and how to work with docker compose in much greater working detail.

In this post we will go a step further to configure selenium grid with docker compose. We have also discussed about configuring and working with Selenium Grid using Docker in greater detail in our executeautomation, please go ahead and read the article from here

Here is the complete video to configure and work with Docker compose for Selenium grid

Identifying broken links with Selenium C#

In this post we will discuss one of the common question asked by many readers of ExecuteAutomation, which is the topic name.

Its actually fairly very simple though, I just wrote 10 lines of code to achieve it (you might have even better solution than one I have)

So, here is the pseudo code

  1. Navigate to the URL of site you are interested in
  2. Get all the links of page using FindElements(By.Tag(“a”)) method
  3. Iterate through the page URLs and get the attributes href using GetAttribute(“href”) method
  4. Use Simple WebRequest and HttpWebResponse class to get the page response and status code.

So, here is the output

Here is the source code

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?
