There are many different types of testing that you can use to make sure that changes to your code are working as expected. Not all testing is equal, though, and we will see here how the main testing practices differ from each other.
Software Testing is a process of evaluating the functionality of a software application to find any software bugs. It checks whether the developed software met the specified requirements and identifies any defect in the software in order to produce a quality product. It is basically executing a. So, keep reading to find the types of software testing you need to make mandatory in your development team, as well as an explanation of how to do it. Unit testing: the first pitfall. When your vacuum cleaner’s blocked, you detach the pipes to find which section the blockage is in. There are many different types of testing that you can use to make sure that changes to your code are working as expected. Not all testing is equal, though, and we will see here how the main testing practices differ from each other.
At a high level, we need to make the distinction between manual and automated tests. Manual testing is done in person, by clicking through the application or interacting with the software and APIs with the appropriate tooling. This is very expensive as it requires someone to set up an environment and execute the tests themselves, and it can be prone to human error as the tester might make typos or omit steps in the test script.
Automated tests, on the other hand, are performed by a machine that executes a test script that has been written in advance. These tests can vary a lot in complexity, from checking a single method in a class to making sure that performing a sequence of complex actions in the UI leads to the same results. It's much more robust and reliable than automated tests – but the quality of your automated tests depends on how well your test scripts have been written.
Automated testing is a key component of continuous integration and continuous delivery and it's a great way to scale your QA process as you add new features to your application. But there's still value in doing some manual testing with what is called exploratory testing as we will see in this guide.
Types Of Software Testing Methods
Unit tests
Unit tests are very low level, close to the source of your application. They consist in testing individual methods and functions of the classes, components or modules used by your software. Unit tests are in general quite cheap to automate and can be run very quickly by a continuous integration server.
Integration tests verify that different modules or services used by your application work well together. For example, it can be testing the interaction with the database or making sure that microservices work together as expected. These types of tests are more expensive to run as they require multiple parts of the application to be up and running.
Functional tests focus on the business requirements of an application. They only verify the output of an action and do not check the intermediate states of the system when performing that action.
There is sometimes a confusion between integration tests and functional tests as they both require multiple components to interact with each other. The difference is that an integration test may simply verify that you can query the database while a functional test would expect to get a specific value from the database as defined by the product requirements.
End-to-end testing replicates a user behavior with the software in a complete application environment. It verifies that various user flows work as expected and can be as simple as loading a web page or logging in or much more complex scenarios verifying email notifications, online payments, etc..
End-to-end tests are very useful, but they're expensive to perform and can be hard to maintain when they're automated. It is recommended to have a few key end-to-end tests and rely more on lower level types of testing (unit and integration tests) to be able to quickly identify breaking changes.
Acceptance tests are formal tests executed to verify if a system satisfies its business requirements. They require the entire application to be up and running and focus on replicating user behaviors. But they can also go further and measure the performance of the system and reject changes if certain goals are not met.
Performance tests check the behaviors of the system when it is under significant load. These tests are non-functional and can have the various form to understand the reliability, stability, and availability of the platform. For instance, it can be observing response times when executing a high number of requests, or seeing how the system behaves with a significant of data.
Performance tests are by their nature quite costly to implement and run, but they can help you understand if new changes are going to degrade your system.
Smoke tests are basic tests that check basic functionality of the application. They are meant to be quick to execute, and their goal is to give you the assurance that the major features of your system are working as expected.
Smoke tests can be useful right after a new build is made to decide whether or not you can run more expensive tests, or right after a deployment to make sure that they application is running properly in the newly deployed environment.
An individual can execute all the tests mentioned above, but it will be very expensive and counter-productive to do so. As humans, we have limited capacity to perform a large number of actions in a repeatable and reliable way. But a machine can easily do that rapidly and will test that login/password combination works for the 100th time without complaining.
To automate your tests, you will first need to write them programmatically using a testing framework that suits your application. PHPUnit, Mocha, RSpec are examples of testing frameworks that you can use for PHP, Javascript, and Ruby respectively. There are many options out there for each language so you might have to do some research and ask developer communities to find out what would be the best framework for you.
When your tests can be executed via script from your terminal, you can have them be automatically executed by a continuous integration server like Bamboo or use a cloud service like Bitbucket Pipelines. These tools will monitor your repositories and execute your test suite whenever new changes are pushed to the main repository.
If you're just getting started with testing, you can read our continuous integration tutorial to help you with your first test suite.

The emulator is a desktop application that emulates a mobile device running Windows 10. Mobile roms download.
The more features and improvements go into your code, the more you'll need to test to make sure that all your system works properly. And then for each bug you fix, it would be wise to check that they don't get back in newer releases. Automation is key to make this possible and writing tests sooner or later will become part of your development workflow.
So the question is whether it is still worth doing manual testing? The short answer is yes, and it should be focused on what is called exploratory testing where the goal is to uncover non-obvious errors.
An exploratory testing session should not exceed two hours and need to have a clear scope to help testers focus on a specific area of the software. Once all testers have been briefed, is up to them to try various actions to check how the system behaves. This type of testing is expensive by nature but is quite helpful to uncover UI issues or verify complex user workflows. It's something especially worth doing whenever a significant new capability is added to your application to help understand how it behaves under edge cases.
To finish this guide, it's important to talk about the goal of testing. While it's important to test that users can use your application (I can log in, I can save an object) it is equally important to test that your system doesn't break when bad data or unexpected actions are performed. You need to anticipate what would happen when a user makes a typo, tries to save an incomplete form or uses the wrong API. You need to check if someone can easily compromise data, get access to a resource they're not supposed to. A good testing suite should try to break your app and help understand its limit.
And finally, tests are code too! So don't forget them during code review as they might be the final gate to production.
What is Software Testing:
Software testing is a process, to evaluate the functionality of a software application with an intent to find whether the developed software met the specified requirements or not and to identify the defects to ensure that the product is defect free in order to produce the quality product.
Let’s see standard definition, software testing types such as manual and automation testing, testing methods, testing approaches and types of black box testing.
Definition:
According to ANSI/IEEE 1059 standard – A process of analyzing a software item to detect the differences between existing and required conditions (i.e., defects) and to evaluate the features of the software item.

Software Testing Types:
Manual Testing:Manual testing is the process of testing the software manually to find the defects. Tester should have the perspective of end users and to ensure all the features are working as mentioned in the requirement document. In this process, testers execute the test cases and generate the reports manually without using any automation tools.
Automation Testing:Automation testing is the process of testing the software using an automation tool to find the defects. In this process, testers execute the test scripts and generate the test results automatically by using automation tools. Some of the famous automation testing tools for functional testing are QTP/UFT and Selenium.
The human resources manual is a key tool which highlights the detailed polices of companies regarding employee management and the long term relationship between the employee and the company’s management. This manual is an essential element in organizations and companies which helps employees to conduct their jobs or tasks accordingly and appropriately without compromising health hazards.
However the Human resources manual describe the workplace practices of employees and also. A handbook which provides brief information related to the safety and care of staff or labor is called employee safety manual and the format which is used to prepare this is called Employee Safety Manual Template. However this manual provides employer a safe exist in case of any unfortunate event occurs with employee/s during office or working hours.

Testing Methods:
- Static Testing
- Dynamic Testing
Static Testing: It is also known as Verification in Software Testing. Verification is a static method of checking documents and files. Verification is the process, to ensure that whether we are building the product right i.e., to verify the requirements which we have and to verify whether we are developing the product accordingly or not.
Activities involved here are Inspections, Reviews, Walkthroughs
Dynamic Testing: It is also known as Validation in Software Testing. Validation is a dynamic process of testing the real product. Validation is the process, whether we are building the right product i.e., to validate the product which we have developed is right or not.
Activities involved in this is Testing the software application

Testing Approaches:
There are three types of software testing approaches.
- White Box Testing
- Black Box Testing
- Grey Box Testing
White Box Testing: It is also called as Glass Box, Clear Box, Structural Testing. White Box Testing is based on applications internal code structure. In white-box testing, an internal perspective of the system, as well as programming skills, are used to design test cases. This testing is usually done at the unit level.
Black Box Testing: It is also called as Behavioral/Specification-Based/Input-Output Testing. Black Box Testing is a software testing method in which testers evaluate the functionality of the software under test without looking at the internal code structure.
Grey Box Testing: Grey box is the combination of both White Box and Black Box Testing. The tester who works on this type of testing needs to have access to design documents. This helps to create better test cases in this process.

Unit Testing: Unit Testing is done to check whether the individual modules of the source code are working properly. i.e. testing each and every unit of the application separately by the developer in the developer’s environment. It is AKA Module Testing or Component Testing
Integration Testing: Integration Testing is the process of testing the connectivity or data transfer between a couple of unit tested modules. It is AKA I&T Testing or String Testing. It is subdivided into Top-Down Approach, Bottom-Up Approach and Sandwich Approach (Combination of Top Down and Bottom Up).
System Testing (end to end testing): It’s a black box testing. Testing the fully integrated application this is also called as end to end scenario testing. To ensure that the software works in all intended target systems. Verify thorough testing of every input in the application to check for desired outputs. Testing of the users experiences with the application.
Acceptance Testing: To obtain customer sign-off so that software can be delivered and payments received. Types of Acceptance Testing are Alpha, Beta & Gamma Testing.
Read more on Levels of Testing.
Types of Black Box Testing:
- Functionality Testing
- Non-functionality Testing
Functional testing:
In simple words, what the system actually does is functional testing. To verify that each function of the software application behaves as specified in the requirement document. Testing all the functionalities by providing appropriate input to verify whether the actual output is matching the expected output or not. It falls within the scope of black box testing and the testers need not concern about the source code of the application.
Non-functional testing:
In simple words, how well the system performs is non-functionality testing. Non-functional testing refers to various aspects of the software such as performance, load, stress, scalability, security, compatibility etc., Main focus is to improve the user experience on how fast the system responds to a request.
There are more than 100 types of testing. You can check this post where we have mentioned 100+ software testing types.
Testing Artifacts:
Test Artifacts are the deliverables which are given to the stakeholders of a software project. A software project which follows SDLC undergoes the different phases before delivering to the customer. In this process, there will be some deliverables in every phase. Some of the deliverables are provided before the testing phase commences and some are provided during the testing phase and rest after the testing phase is completed.
Some of the test deliverables are as follows:
- Test plan
- Traceability matrix
- Test case
- Test script
- Test suite
- Test data or Test Fixture
- Test harness

Why do we need Software Testing
Interviewers may ask you this question like “Why do we need Software Testing” or “Why is testing required” or “Why Software Testing”.
When I started in software testing I had no idea what software testing is and why it is required. I also had no clue of where to start. May be you are in the same situation as I was long back. I say, Software Testing is an art to evaluate the functionality of a software application with an intent to find whether the developed software met the specified requirements or not and to identify the defects to ensure that the product is defect free in order to produce the quality product.
What if there is no Software Testing in the Software Development process.
As per the current trend, due to constant change and development in digitization, our lives are improving in all areas. The way we work is also changed. We access our bank online, we do shopping online, we order food online and many more. We rely on software’s and systems. What if these systems turnout to be defective. We all know that one small bug shows huge impact on business in terms of financial loss and goodwill. To deliver a quality product, we need to have Software Testing in the Software Development Process.
Some of the reasons why software testing becomes very significant and integral part in the field of information technology are as follows.
Types Of Software Testing Tutorialspoint
- Cost effectiveness
- Customer Satisfaction
- Security
- Product Quality
1. Cost effectiveness
As a matter of fact design defects can never be completely ruled out for any complex system. It is not because developers are careless but because the complexity of a system is intractable. If the design issues go undetected, then it will become more difficult to trace back defects and rectify it. It will become more expensive to fix it. Sometimes, while fixing one bug we may introduce another one in some other module unknowingly. If the bugs can be identified in early stages of development then it costs much less to fix them. That is why it is important to find defects in the early stages of the software development life cycle. One of the benefits of testing is cost effectiveness.
It is better to start testing earlier and introduce it in every phase of software development life cycle and regular testing is needed to ensure that the application is developed as per the requirement.
2. Customer Satisfaction
In any business, the ultimate goal is to give the best customer satisfaction. Yes, customer satisfaction is very important. Software testing improves the user experience of an application and gives satisfaction to the customers. Happy customers means more revenue for a business. One of the reasons why software testing is necessary is to provide the best user experience.
3. Security
This is probably the most sensitive and vulnerable part of software testing. Testing (penetration testing & security testing) helps in product security. Hackers gain unauthorized access to data. These hackers steal user information and use it for their benefit. If your product is not secured, users won’t prefer your product. Users always look for trusted products. Testing helps in removing vulnerabilities in the product.
4. Product Quality
Software Testing is an art which helps in strengthening the market reputation of a company by delivering the quality product to the client as mentioned in the requirement specification documents.
Due to these reasons software testing becomes very significant and integral part of Software Development process.
Now let’s move ahead and have a look at some of the principles of Software Testing.
Principles of Software Testing:
Testing of software consist of some principles that play a vital role while testing the project.
The Principles of Software Testing are as follows :
- Testing shows presence of defects
- Exhaustive testing is impossible
- Early testing
- Defect clustering
- Pesticide paradox
- Testing is context dependent
- Absence of error – fallacy
