and for testing periods it may include detailed step-by-step test cases.
Some advantages which manual testing offers are-

Cost-Effective

It may save the costs of using automatic tools to test software.

Advantage of human eye

Automated tool might unsee some but human eye catches that and that can be immediately be rectified by the tester. Automated tool can’t be relied entirely to provide you with the best user experience, like visual or design bugs, can be identified more effectively by the human eye. The advantage of flexibly rectifying bugs is added in manual testing.

2- Automation Testing

Automation Testing is done by using testing software and to assist you in automatically testing your software there are various tools accessible

Scheduled test execution

Scheduling a software test anytime during the day from anywhere can be done using automation testing and you don’t have to be physically present for the testing as this provides flexibility which automation tools do

Regression testing is easy

Running functional and non-functional tests repeatedly to ensure the smooth functioning of the software after a change has been made is referred to as regression.
Scheduling and conduction of the regression test can be performed automatically at any time using automation testing. Automation testing enables to reuse the test scripts

Time Saving

As you do not have to overlook the testing process so automation testing increases the speed. A lot of time which takes on testing scripts and repeated
testing gets freed which leads to efficiency and offering you a chance to work on other aspects of the software.

Things which it describes are

Test Strategy

Test Objective

Test Criteria

Resource Planning

Schedule & Estimation

Test Estimation

It is a document that estimates the amount of effort needed in the project while the whole project is divided into smaller components where each component’s required effort is estimated. The formation of a test-schedule is lead by Test Estimation which is also known as project management.

Test Scenario

It is an elaborate document of test cases that includes all functionalities of the software and similar requirements are grouped to be performed. Generally, from user’s point of view test scenarios are prepared. Test Scenarios are prepared from the user’s viewpoint; therefore, it is preferable to take inputs from clients, developers or users. It is easy to maintain, as the modification of test scenarios is convenient and independent. 

Test Cases

To evaluate one feature of the software, test cases are performed which are a group of actions. Test cases are generally derived from test scenarios. Test cases which assist the testing team in ensuring that the actual and expected results match include particular conditions.

Test Data

The data used to perform tests refers to Test Data. To find errors and bugs properly, it needs to be accurate and comprehensive.

Requirement Traceability Matrix

It assists the testing team in setting every requirement with a test case and helps the testing team to ensure that all the needs of the client have been met. To check on the testing process quickly, it comes as very helpful to clients.

Test Summary Report

Incident Report

An incident report is generally made when a bug is found while executing the final software.

What are the Principles of Software Testing?

Testing shows the presence of defects

Exhaustive testing is not possible

Early Testing: Testing should be started early to find detects first

Defect Clustering: A small number of modules usually contain most of the defects

Pesticide Paradox: Repeatedly conducting the same tests won’t find new flaws. Test cases should be regularly reviewed and revised to avoid the pesticide paradox

Testing is context-dependent

Absence of errors fallacy – Identifying and fixing bugs is useless if the system built is unusable

What qualities should you look for in your Software testing team

Contextual Adaptivity

Openness to adapt different software testing approaches according to the project’s context, is the foremost thing a testing team must has, as such flexibility comes in handy to increase the efficiency of the software.

Programming Knowledge

The testing team should have a certain amount of programming knowledge to assess and rectify the bugs more effectively, no matter what testing type is being used.

Understanding of Testing Techniques

Hired testing team must have knowledge of the variety of testing techniques available and has a fair idea about all the options available.

Understanding Business Requirements

A testing team must be having a clear understanding of the purpose of the software being tested, as being aware of client’s requirement can gain them upper hand in identifying and rectify bugs in a better way.

Good Communication Skills

The team must possess exceptional verbal and written communication skills to eliminate the scope of misunderstandings in the requirements, as it can directly affect the understanding between the testing team and the client, therefore is very crucial. 

Constant Learning

Being a constant learner is always helpful as, world is transforming digitally, new technologies and techniques are introduced every day. Therefore, remaining open to learning to stay updated about all the latest available options, this will help them do a better job.
