In the software development process, it is customary to find errors. It’s not a significant inconvenience when this happens at the software testing stage.
Continuing not to address them can lead to severe problems for all parties involved in the project development process. Software testing plays a fundamental role and guarantees the quality of the utmost importance for any company.

What is Software Testing?
Software testing, or QA software, is a process for verifying and validating a software program or application’s functionality to ensure that the software product is free of defects. The final intention is that it matches the expected requirements to deliver a quality product. It involves running software or system components using manual or automated tools to evaluate one or more properties of interest.
Software testing is a parallel process to software development whose tasks must be carried out as the product is built to avoid problems in functionality before its release.
Why is Software Testing Necessary?
Software testing is significant because it lets you identify early if there are any problems in the software. Facilitating its resolution before the delivery of the product. An adequately tested software product ensures quality, security, reliability. high performance and other benefits such as time savings, safety, and customer satisfaction.
Objectives of Software Testing
- Detect and correct errors.
- Provide software quality and reliability.
- Ensure the correct functionality of the product.
- Avoid future mistakes.
- Facilitate decision-making to move to production developments that do not contain errors.
- Meet business requirements and user satisfaction.
- Avoid the appearance of new defects in the future that may affect the software.
Types of Tests
Software testing is mainly classified into two key categories: functional testing and non-functional testing. Also, there is a third type of test called a maintenance test.
- Functional testing: However, They verify each function of an app or software and its functionality with a specific set of requirements.
- Non-functional or performance testing: Consider reliability, usability, and performance parameters.
- Maintenance (regression and maintenance).
Functional Tests:
- Unit testing: It is a way to test a smaller unit or piece of code that can be logically isolated in a system.
- Integration testing: Test the integration or interfaces between components, and interactions with different system parts, such as file system and hardware, operating system, or interfaces between systems.
- System testing: Evaluates how the different components of an application interact together in the complete and integrated system or application.
- Sanity testing is a quick and essential test to determine if a particular application or component behaves correctly.
- Smoke testing: This initial testing process verifies the core functionality to ensure it is ready for further testing.
- Interfaced testing: Verifies the communication between two different software systems by checking the authentication of the established connection.
- Reversion testing: Ensures that an application continues to perform as expected after any code update, change, or improvement.
- Beta/acceptance testing: performed on a product or prototype before marketing or delivery to decide whether specifications or contract have been met. It ensures that the quality and design of the product meet the requirements in terms of functionality, usability, durability and safety.
Non-Functional Tests:
- Moreover, Performance testing: Evaluates the performance, speed, or responsiveness of the application being tested under the required workload.
- Load testing: Tests the behavior of an application under a heavy workload.
- Stress Testing: Stress tests determine the robustness of the software by evaluating regular operation under hefty load conditions, thus ensuring that the software does not crash in critical situations.
- Volume Testing: Tests the performance of the by loading when processing large volumes of data.
- Security Testing: Checks whether the system is protected against sudden or deliberate attacks from internal and external sources.
- Compatibility Testing: Check if the application is compatible with different environments.
- Install Testing: Checks whether the soft works as expected after installation.
- Recovery: Determines whether a system can recover from failures or not.
- Reliability: Ensures that the soft works consistently by performing a task without failing within a specific period.
- Usability: Test the user’s ease of operation, learning and preparing inputs and outputs.
- Compliance: Determines whether a soft program or system meets a defined set of internal or external standards before the production release.
- However, Localization Testing: Verifies the behavior of a product according to specific local or cultural environments.
Conclusions About Software Testing
The involvement of a quality team (QA) during the phases of a product development process is considerer critical to delivering the best product.
Software with defects can cause the loss of business; therefore, it is vital to detect errors before delivery or to move to production.
