Cucumber – bridge or another one abyss between BA and QA

Cucumber Introduction:

Cucumber is a tool based on Behavior Driven Development (BDD) framework which is used to write acceptance tests for web application. It allows automation of functional validation in easily readable and understandable format (like plain English) to Business Analysts, Developers, Testers, etc.

Cucumber feature files can serve as a good document for all. There are many other tools like JBehave which also support BDD framework. Initially Cucumber was implemented in Ruby and then extended to Java framework. Both the tools support native JUnit.

Behavior Driven Development is extension of Test Driven Development and it is used to test the system rather than testing the particular piece of code. We will discuss more about the BDD and style of writing BDD tests.

Cucumber could be used along with Selenium and Java and this is more than enough to make me happy.

Cucumber Basics:

In order to understand cucumber we need to know all the features of cucumber and its usage.

#1) Feature Files:

Feature files are essential part of cucumber which is used to write test automation steps or acceptance tests. This can be used as live document. The steps are the application specification. All the feature files ends with .feature extension.

Sample feature file:

Feature: Login Functionality Feature
In order to ensure Login Functionality works,
I want to run the cucumber test to verify it is working
Scenario: Login Functionality
Given user navigates to SOFTWARETETINGHELP.COM
When user logs in using Username as “USER” and Password “PASSWORD”
Then login should be successful
Scenario: Login Functionality
Given user navigates to SOFTWARETETINGHELP.COM
When user logs in using Username as “USER1” and Password “PASSWORD1”
Then error message should be thrown

QA terms and questions

What are different types of software testing?

Note: Except the Shakeout testing and Unit testing which are respectively done by the CMT and Coder/Developer, all other testing are done by the QA Engineer (Tester).

1) Unit testing: It is a test to check the code whether it is properly working or not as per the requirement.  It is done by the developers (Not testers).

2) Shakeout testing: This test is basically carried out to check the networking facility, database connectivity and the integration of modules. (It is done by the Configuration Team)

3) Smoke testing: It is an initial set of test to check whether the major functionalities are working or not and also to check the major breakdowns in the application. It is the preliminary test carried out by the SQA tester.

4) Functional testingal It is a test to check whether each and every functionality of that application is working as per the requirement. It is major test where 80% of the tests are done. In this test, the Test Cases are ‘executed’.

5) Integration testing: It is a test to check whether all the modules are combined together or not and working successfully as specified in the requirement

6) Regression testing: When a functionality is added to an application, we need to make sure that the newly added functionality does not break the application.  In order to make it sure, we perform a repeated testing which is called Regression Testing.  We also do regression testing after the developers fix the bugs.  See the video below for more understanding. (Courtesy of guru99.com).

7) System testing: Testing which is based on overall requirements specification and it covers all combined parts of a system. It is also a black box type of testing. System testing is black box testing, performed by the Test Team, and at the start of the system testing the complete system is configured in a controlled environment. System testing simulates real life scenarios that occur in a “simulated real life” test environment and test all functions of the system that are required in real life. Upon completion of integration testing, system testing is started. Before system testing, all unit and integration test results are reviewed by Software QA to ensure all problems have been resolved.

8) Load testing: It is a test to check the user’s response time of number of users using any one scenario (single business process) of the same application at the same time.

9) Stress testing: In this type of testing the application is tested against heavy load such as complex numerical values, large number of inputs, large number of queries etc. which checks for the stress/load the applications can withstand.

10) Performance testing: It is a test to check the user’s response time of number of users using multiple scenarios (multiple business process) of the same application at the same time. Continue reading

Test Framework build 1.0

So, my latest and greatest framework build is ready (available at BickBucket, I could share the access, but it will be no core test methods, cause they came from my work and I can’t share them). This is a link to the overall description of the very first version of it. Framework available for every QA in my company and instructions, manuals, key method descriptions and examples provided, for example:

  • Which method validates that alerts and warnings exists (with expected message) and how to close them.
  • Which one method hides/shows grid columns
  • Which one method checks special characters/too long value/empty value input into the text fields
  • Which method and how add/validates date or number fields input
  • Which one method opens row menu
  • Which one validates that value exists in the grid
  • And tens of others

I successfully made TeamCity project to run test suites for some of our components and every QA could create test and upload them to the test library:

Test Suite Report Builder Comparison

Here is a short comparison of for most popular ways to build test report for TestNG + Java framework (with comparison table in the end of the post).

Log4J

This is a pretty simple logger which throws test suite execution to the Windows Console, Eclipse Console and text file.

There is no screenshot capturing or easy navigation between multiple suites, so, this is just a huge text file.

Test Framework (Java, TestNG, ANT, etc)

Introduction to Automation testing:

Testing is an essential part of a software development process. While testing intermediate versions of products/projects being developed, testing team needs to execute a number of test cases. In addition, prior to release every new version, it is mandatory that the version passed through a set of “regression” and “smoke” tests. Most of all such tests are standard for every new version of product/project, and therefore can be automated in order to save human resources and time for executing them.

Benefits of using automated testing are the following:

  • Reduction of tests’ time execution and human resources required
  • Complete control over the tests’ results (“actual results” vs “expected results”)
  • Possibility to quickly change test’s preconditions and input data, and re-run the tests dynamically with multiple sets of data

Automation workflow for the application can be presented as follows:

  • First of all it is required to identify tasks that an application has to accomplish.
  • Second, a set of necessary input data has to be created.
  • Third, expected results have to be defined in order one can judge that an application (a requested feature) works correspondingly.
  • Fourth, Executes a test.
  • Finally, Compares expected results with actual results, and decides whether the test has been passed successfully.

Goal:

The goal of this framework is to create a flexible and extendable automated testing framework, which should expand test coverage for as many solutions as possible. Framework must have input and output channels and library of methods to work with UI.

Environment Specifications:

  • Selenium Webdriver. Selenium is a suite of tools for cross-platform automated testing of web applications. It runs on many browsers and operating systems and can be controlled by many programming languages and testing frameworks. Selenium WebDriver is a functional automation tool to automate the applications. It makes direct calls to the browser using each native support for automation.
  • Eclipse IDE. Eclipse is an integrated development environment (IDE) used in computer programming, and is the most widely used Java IDE. It contains a base workspace and an extensible plug-in system for customizing the environment. Eclipse is written mostly in Java and its primary use is for developing Java applications.
  • Java.
  • TestNG. Is a testing framework inspired from JUnit and NUnit. It has extended new functionalities, which made it more powerful and easier than the other testing frameworks. It supports ReportNG (simple HTML reporting plug-in) and XLST (Graphical / Pictorial reports) plug-ins to customize or extend the default TestNG reporting style. TestNG also provides ability to implement ‘IReporter’ an interface which can be implemented to generate a Customized TestNG report by users. It has ‘generateReport()’ method which will be invoked after all the suite has completed its execution and gives the report into the specified output directory.
  • Apache Ant is a Java library and command-line tool whose mission is to drive processes described in build files as targets and extension points dependent upon each other. The main known usage of Ant is the build of Java applications.
  • AutoIT Tool used to handle Windows popups for Document Uploads and Downloads.
  • Apache POI to perform operations with excel like read, write and update the excel sheet
  • Webdriver is a driver that contains programming interface for controlling all kinds of possible actions in browser.
  • Selenium TakesScreenshot to take screenshot in case of error.
  • Log4j is a reliable, fast and flexible logging framework (APIs) written in Java, which is distributed under the Apache Software License.
  • JDBC. Java Database Connectivity (JDBC) is an application programming interface (API) for the programming language Java, which defines how a client may access a database. It is part of the Java Standard Edition platform, from Oracle Corporation.
