1. Smoke Testing

Smoke Testing is done to make sure that the software under testing is ready or stable for further testing 
It is called a smoke test as the testing of an initial pass is done to check if it did not catch fire or smoke in the initial switch-on. 

Example: 

If the project has 2 modules so before going to the module make sure that module 1 works properly.

Advantages of Smoke Testing

1. Smoke testing is easy to perform.
2. It helps in identifying defects in the early stages.
3. It improves the quality of the system.
4. Smoke testing reduces the risk of failure.
5. Smoke testing makes progress easier to access.

2. Sanity Testing

It is a subset of regression testing. Sanity testing is performed to ensure that the code changes that are made are working properly. Sanity testing is a stoppage to check whether testing for the build can proceed or not. The focus of the team during the sanity testing process is to validate the functionality of the application and not detailed testing. Sanity testing is generally performed on a build where the production deployment is required immediately like a critical bug fix. 

Advantages of Sanity Testing

• Sanity testing helps to quickly identify defects in the core functionality.
• It can be carried out in less time as no documentation is required for sanity testing.
• If the defects are found during sanity testing, the project is rejected which is helpful in saving time for execution of regression tests.
• This testing technique is not so expensive when compared to another type of testing.
• It helps to identify the dependent missing objects.

3. Regression Testing

The process of testing the modified parts of the code and the parts that might get affected due to the modifications ensures that no new errors have been introduced in the software after the modifications have been made. Regression means the return of something and in the software field, it refers to the return of a bug.

Advantages of Regression Testing

• It ensures that no new bugs have been introduced after adding new functionalities to the system.
• As most of the test cases used in Regression Testing are selected from the existing test suite, and we already know their expected outputs. Hence, it can be easily automated by the automated tools.
• It helps to maintain the quality of the source code.

4. Acceptance Testing

Acceptance testing is done by the customers to check whether the delivered products perform the desired tasks or not, as stated in the requirements. We use Object-Oriented Testing for discussing test plans and for executing the projects.

Advantages of Acceptance Testing

1. This testing helps the project team to know the further requirements of the users directly as it involves the users for testing.
2. Automated test execution.
3. It brings confidence and satisfaction to the clients as they are directly involved in the testing process.
4. It is easier for the user to describe their requirement.
5. It covers only the Black-Box testing process and hence the entire functionality of the product will be tested.

5. User Acceptance Testing

User Acceptance Testing is a testing methodology where clients/end users participate in product testing to validate the product against their requirements. It is done at the client’s site on the developer’s site. For industries such as medicine or aerospace, contractual and regulatory compliance testing, and operational acceptance tests are also performed as part of user acceptance tests. UAT is context-dependent and UAT plans are prepared based on requirements and are not required to perform all kinds of user acceptance tests and are even coordinated and contributed by the testing team.

6. Exploratory Testing

Exploratory Testing is a type of software testing in which the tester is free to select any possible methodology to test the software. It is an unscripted approach to software testing. In exploratory testing, software developers use their learning, knowledge, skills, and abilities to test the software developed by themselves. Exploratory testing checks the functionality and operations of the software as well as identifies the functional and technical faults in it. Exploratory testing aims to optimize and improve the software in every possible way.

Advantages of Exploratory Testing

• Less preparation required: It takes no preparation as it is an unscripted testing technique.
• Finds critical defects: Exploratory testing involves an investigation process that helps to find critical defects very quickly.
• Improves productivity: In exploratory testing, testers use their knowledge, skills, and experience to test the software. It helps to expand the imagination of the testers by executing more test cases, thus enhancing the overall quality of the software.

7. Adhoc Testing

Adhoc testing is a type of software testing that is performed informally and randomly after the formal testing is completed to find any loophole in the system. For this reason, it is also known as Random or Monkey testing. Adhoc testing is not performed in a structured way so it is not based on any methodological approach. That’s why Adhoc testing is a type of Unstructured Software Testing. 

Advantages of Adhoc testing

• The errors that can not be identified with written test cases can be identified by Adhoc testing. 
• It can be performed within a very limited time. 
• Helps to create unique test cases. 
• This test helps to build a strong product that is less prone to future problems. 
• This testing can be performed at any time during Softthe ware Development Life Cycle Process (SDLC)

8. Security Testing

Security Testing is a type of Software Testing that uncovers vulnerabilities in the system and determines that the data and resources of the system are protected from possible intruders. It ensures that the software system and application are free from any threats or risks that can cause a loss. Security testing of any system is focused on finding all possible loopholes and weaknesses of the system that might result in the loss of information or repute of the organization.

Advantages of Security Testing

1. Identifying vulnerabilities: Security testing helps identify vulnerabilities in the system that could be exploited by attackers, such as weak passwords, unpatched software, and misconfigured systems.
2. Improving system security: Security testing helps improve the overall security of the system by identifying and fixing vulnerabilities and potential threats.
3. Ensuring compliance: Security testing helps ensure that the system meets relevant security standards and regulations, such as HIPAA, PCI DSS, and SOC2.

9. Globalization Testing

Globalization Testing is a type of software testing that is performed to ensure the system or software application can function independently of the geographical and cultural environment. It ensures that the application can be used all over the world and accepts all language texts. Nowadays with the increase in various technologies, every software product is designed in such a way that it is a globalized software product. 

Benefits of Globalization Testing

• Helps to create scalable products: It makes the software product more flexible and scalable.
• Save time: It saves overall time and effort for software testing.
• Reduce time for localization testing: Globalization testing helps to reduce the time and cost of localization testing.

10. Regression Testing

Regression testing is a method of testing that is used to ensure that changes made to the software do not introduce new bugs or cause existing functionality to break. It is typically done after changes have been made to the code, such as bug fixes or new features, and is used to verify that the software still works as intended.

Regression testing can be performed in different ways, such as:

• Retesting: This involves testing the entire application or specific functionality that was affected by the changes.
• Re–execution: This involves running a previously executed test suite to ensure that the changes did not break any existing functionality.
• Comparison: This involves comparing the current version of the software with a previous version to ensure that the changes did not break any existing functionality.

Advantages of Regression Testing

• It helps to ensure that changes made to the software do not introduce new bugs or cause existing functionality to break.
• It helps to ensure that the software continues to work as intended after changes have been made.
• It helps to improve the overall reliability and stability of the software.
• It’s important to keep in mind that regression testing is an ongoing process that should be done throughout the software development
• lifecycle to ensure that the software continues to work as intended. It should be automated as much as possible to save time and resources. Additionally, it’s important to have a well-defined regression test suite that covers

Every time a new module is added leads to changes in the program. This type of testing makes sure that the whole component works properly even after adding components to the complete program. 

Example:

In school records, suppose we have module staff, students, and finance combining these modules and checking if the integration of these modules works fine in regression testing.

11. Smoke Testing

Smoke Testing is done to make sure that the software under testing is ready or stable for further testing 
It is called a smoke test as the testing of an initial pass is done to check if it did not catch fire or smoke in the initial switch-on. 

Example: 

If the project has 2 modules so before going to the module make sure that module 1 works properly.

12. Alpha Testing

Alpha testing is a type of validation testing. It is a type of acceptance testing that is done before the product is released to customers. It is typically done by QA people. 

Example: 

When software testing is performed internally within the organisation.

13. Beta Testing

The beta test is conducted at one or more customer sites by the end-user of the software. This version is released for a limited number of users for testing in a real-time environment.

Example: 

When software testing is performed for the limited number of people.

14. Object-Oriented Testing

Object-Oriented Testing testing is a combination of various testing techniques that help to verify and validate object-oriented software. This testing is done in the following manner: 

• Testing of Requirements,
• Design and Analysis of Testing,
• Testing of Code,
• Integration testing,
• System testing,
• User Testing.
