automation testing using python tutorial | python automation testing

Automation testing using python tutorial : In this tutorial, we are going to discuss the automation testing in detail. It is testing the software using the automation tool to execute the test case suite. This technique is used to implement the life cycle of software in less time and provide the effectiveness to test software. The automation testing use tool to execute test case and no human involvement is present here. The tester will write a test case and script using an automation tool. The goal of automation testing is to increase test efficiency and the development of software costs.
The test automation will involve using a tool to test the software. There is a difference between automation and manual but both are important for testing. The testing is important to the software development levels of experience and testing. The tools and machines are used to control the execution of tests and compare the outcome. Hazen is the inventor of the automation testing and use tool to automate the testing process of application.

History of automation testing:-

Basically, the test automation is invented in the companies having large database systems to test systems at the development cycle.
The first generation of automation testing is introduced by the use of GUI they are capable of performing playback functions.
Replacing human activity by devices that will enhance efficiency, the time has limited resources.
We have an example of the Amazon Company for Pickup and drop by delivery drones.
There are many examples based on automated software testing and provide the technical topics.
The software testing is a process which ensures that actual output matches the desired output.
The testing of software is very important because it helps the developer to find out bugs in software in less time.

The python programming language has the tools and libraries to help automated tool for application.
There are two types of testing the software as,

Manual testing:-

It means the testing is performed by sitting the human in front of the computer and executing test steps.

Automation testing:-

This testing is called automatic testing as the testers write test scripts on their own and use the software to test.
It means using the tool for testing the application.
Need for automation testing:-
If the software is released in a market with bug fixed and new release.
It becomes difficult to remove the bugs and erros.Also very costly to remove the errors and loss of the quality an application.
So we need good testing to find out bugs in the early stage of releasing the application.
Types of testing the software which can be automated:-

1. Data-driven testing
2. Regression testing
3. Black box testing
4. Smoke testing
5. Keyword test

Automation tools are used as follows:-

1. For analysis of data
2. Scenario modeling
3. Data generation and modeling
4. Reporting purpose
5. Test management and execution

Steps of the automation testing tool selection:-

1. Entering the test data into SUT and compare expected and actual results.
2. Then the test report is generated.
3. The same test suite is repeatedly done here.
4. So the automation tool is used to record test suit.
5. The tool is used to record the test suit and replay it.
6. After automation no human intervention is needed.

Steps to follow automation testing:-

1. To identify the area with software and automate.
2. Then we have to choose the tool for test automation.
3. After that we write the test scripts.
4. Then develop the test suits.
5. Building the result report is carried out.
6. Then find out possible bugs and the performance issue.

Types of tools for Automation testing are:-

1. WATIR
2. HP quick test professional
3. Selenium
4. Visual studio test professional
5. Test complete
6. Silk test

Need for automation testing:-

In manual testing, some negative scenarios, money-consuming of workflow will result in automation testing needs. No need of human beings so you can run the automation testing overnight. It increases the seed of test execution. The test converges increases in automation testing. Manual testing is boring and error prone so automation is preferred.
1. Test tool selection in automation testing:-
The tool selection has criteria and that include automation task, and budgets that satisfy the needs.

2 Define the scope of automation following fact:-

The points as frameworks that support scripts and less maintenance also high returns by high investment.

3 Test execution:-

The text execution takes place in this phase and depends on the language such as .NET also by using Nunit for java and Qunit or jasmine

4 Maintenance:-

Used for creating reports for the generation of tests and should be documented and referred in the future.
5. Planning, design, and development:-
We need to install frameworks or libraries.
Designing and the development of test case is developed such as Junit, Nunit, and Qunit.

Use of Framework in automation testing:-

1. Used to maintain consistency of testing
2. Then improving the structuring of the test.
3. The less maintained code
4. The reuse is improper

Frameworks in automation testing are:-

1. Linear scripting framework:-

Used for the replaying and recording test scripts in a sequential manner with no modifications.
2. Keyword driven framework:-
The tables on the spreadsheet which specify the action of test script based on the library for a single keyword.
3. Data-driven framework:-
The source of test criteria which specifies the test script to run.
4. Modular testing:-
The modules of AUT are divided and then tested with a test script that is combined for the large test script.
5. Hybrid testing framework:-
Combination of the frameworks to leverage the strength of each and test.
The test automation services:-
The Capgemini will offer automation services as,

1. Used for evaluation and recommendations.
2.  Test automation for scripting and execution purposes.
3. The regression testing
4. For framework implementation
5. The Assessment and ROI evaluation.

Benefits of automation testing:-

1. It saves money
2. Also increase productivity
3. Reduce the testing time
4. Increases the testing coverage area.
5. Support many applications
6. Simplify execution
7. Reliability is increased
8. The improvement to the tool
9. Develop the value of software
10. The boring task is eliminated.

Skills required for automation testing using python :-

1. Good programming knowledge:-
To start the automation testing we should have knowledge of automation testing.Also need some programming knowledge of the automation scripts.

2. Excellent manual testing skills:-
The automation testing is a machine and it will do what we tell.
Complicated tasks will need preparation and planning.
Manual testing will result in negative and positive test cases.
To understand the problem we need manual testing.
3. We should know the automation tool:-
There is more demand for the best quality and less testing time.
The tools to be learned are selenium, HP-Uft, soapUI, etc.
4. Selenium:-
The tool will ensure flawless execution of web-based applications for automation testing.
The selenium tool should be familiar with the experienced or fresher candidates.
5. HP-UFT:-
It is also called QTP and the tool is by HP which is best ensures automation functional regression of application.
6. SoapUI:-
This tool is best for API and web services which supports REST and SOAP services.
7. Apache JMeter:-
Used for measuring the load testing and performance of the application.
Also used for API and service testing application and popular tools.

Understanding business requirements:-

The API services used to connect the system and use it.
The use of programming language by the development tool
The database needs to store backend information along user data
The time spends by the manual tester while testing applications.
The delivery date which is expected should be fulfilled.

Automation testing for web applications:-

Here the meaning of web applications means the applications that run in web browsers.
They include client-server application, the client /browser will send request and response is received by the web server.
They are configured to execute client request and provide a response using the programs in web programming lie java, python, PHP, etc
This testing is suitable sue to the requirements for testing applications.
The testing can be performed as performance testing, functional testing, and different testing.
The selenium tool is used to execute the test performance and functionality of theb application repeatedly. 

Automation Testing for Mobile Applications:-

The mobile OS is the ios and android also have a market with huge installations.
 Accessing the application is easy on the small screen with clicks on touch screen mobile phones.
These operating systems are developed over a short period of time and have challenges for software testing.
The configurations in software and hardware are combined by the testing team.
While software testing for the mobile application the challenges faced are,

1. The version of mobile operating systems
2. Multiplicity in screen size
3. Changes in application

The HP QTP will use Visual basic script for automation applications.
It is installed as available in Windows OS.
The QTP is a functional testing tool best for regression testing applications.
The important tool available in the market and used for testing.

Difference in manual and automation testing:-

Advantages of automation testing using python :-

1. It decreases the time and repetitive task.
2. The resource is less and human effort is required
3. It reports after testing large data.
4. Test a large number of users at a time.
5. Help to analyze the system to check performance.

Disadvantages of automation testing

• Not flexible ad does what is designed
• The tool used for testing is costly
• To test user interface human element s necessary
• Debugging the test script is also considered in automation testing.
