Selenium testing or manual testing ?

Manual Testing is a process carried out to find the defects. In this method, the tester plays an important role as the end user and verify all features of the application to ensure that the behavior of the application. The Manual Testing is a very basic type of testing which helps to find the bugs in the application under test. It is preliminary testing, must be carried out prior to starting automating the test cases and also needs to check the feasibility of automation testing. The test plan is created & followed by the tester to ensure that the comprehensiveness of testing while executing the test cases manually without using automation testing tool.

It is not necessary to have knowledge of any testing tool for manual software testing. As the Software testing fundamental always says that “100% Automation is not possible” so the Manual Testing is very important.

The main Goal of Manual Testing is to make sure that the application under test is defect free and the software application is working as per the requirement specification document.

This type includes the testing of the Software manually i.e. without using any automated tool or any script. In this type, tester takes over the role of the end user and test the Software to identify any unexpected behavior or bug. There are different stages of manual testing like Unit testing, Integration testing, System testing and User Acceptance testing.

A test plan document is created by test lead which describes the detailed and systematic approach to testing a software application. Basically, the test plan typically includes a complete understanding of what the ultimate workflow will be. To ensure the completeness of testing (100% test coverage) test cases or test scenarios are created. Manual Testing Concepts also includes exploratory testing as testers explore the software to identify errors in it

After the testing is started the designed test cases or test scenarios will be executed & any differences between actual & expected results are reported as defects. Once the reported defects are fixed, the testers will retest the defect to make sure that the defects are fixed. The main goal of Software testing is to make software defect free & deliver good quality Product to the customer.

Executing the test cases without any tools is known as manual testing.

Execting the test cases using aotomation tools is knowna s selenium testing.

Manual Testing is the process of testing the software manualy 

Manual testing is the process of manually testing software for defects. It requires a tester to play the role of an end user and use most of all features of the application to ensure correct behavior of the software.

Whereas Automation testing (Selenium)

Automation Testing means using an automation tool to execute your test case suite.   The automation software can also enter test data into the System Under Test ,  compare  expected and actual  results and generate detailed test  reports.

Test Automation demands considerable investments of money and resources. Successive development cycles will require execution of same test suite repeatedly. Using a test automation tool it's possible to record this test suite  and re-play it  as required. Once the  test suite is automated,  no human intervention is required .

Manual testing is the first step towards testing. One will have the exact idea how and what to test over an application. Manual testing have many sub-types according to the scope and phase of testing which is available everywhere.

Selenium testing on the other is automating repeatitive tasks. Selenium is an application to test the application. Mostly web applications can be automated with Selenium. For creating a good test with selenium one should know manual testing.

So, for a beginner manual testing is good and the next step may be automation using tools like Selenium, Postman etc. 

Testing the features or functionalities of an application or software manually in order to find defects or bug in it.

Manual testing is also known as Mother of all testing because whatever the application we get first we have to test it manually , if application is stable then only we need to automate it if it is necessary.

Selenium is a tool which is used to automate "web based applications" during automation testing.

Core java is the programming language used to write develop script in selenium tool.

We switch to automation testing when we are unable to achieve the task in the given period of time by testing manually. So in order to save time and to make sure application to work efficiently.

Manual Testing:-Manual Testing is evaluation of a product or component to meet its specific requirement manually.

In manual testing we can find more bugs comparing to automation testing and also in manual testing we can do negative testing but it is very difficult in case of selenium testing.

Manual testing is repetitive and time consuming

Selenium Testing:-Selenium Testing is an open source automation testing for "Web Based Application".

It is performed when the application is stable.

It is used to perform functional and regression testing.

Selenium Testing is a part of  Automation testing which can be used to automate "Web Based" Application. Automation testing is required where we have to perform repetitve tasks. It need basic knowledge of  Programming languages like Java, C#, Python etc. Automation testing plays an important role saving testing time, Manual testing has  equal amount of importance because we cannot automate the test case until and unless build stable and to define stability of build we need to perform manual testing. Testing of any revenue impacting functionlaity is performed manually to make sure it is working properly.  

manual testing

Manual testing is a method used by software developers to run tests manually.

There are many manual testing types which are carried out manually as well as automatically. These are,

Black Box Testing – It is a testing method to test functionalities and requirements of the system. It does not test the internal part of the system.

White Box Testing – It is a testing method based on information of the internal logic of an application’s code and also known as Glass box Testing. It works on Internal working code of the system. Tests are based on coverage of code statements, branches, paths, conditions.

Integration Testing – Integrated modules testing method to verify joint functionality after integration. Modules are typically code modules, individual applications, client and server applications on a network, etc. This type of testing is especially applicable to client/server and distributed systems.

Selenium Testing is an Automated testing which is used to automate "Web Based" Application. Automation testing is mainly used when we need to automate repetitve tasks. It requires a fair amount of knowledge in any of the OOPS Programming language like Java, C#, Python and so on. Although Automation Testing is essential, Manual testing holds its importance as well . As there are many critical and complex modules in an application, it is always preferred to manually test it. A person with a Domain Knowlegde and analytical thinking can be a manual testing.

If you have to choose between Automation(Selenium or QTP) and Manual Testing, I would suggest Automation Testing as it is always in demand. Since, An automation tester can also manually test an application, it is only logical for any company to prefer and automation tester in many scenarios.
