Data controls the entire planet. In all industries, it is gathered, analyzed, and used to inform crucial business choices. However, how can you be certain that your data is reliable, secure, and consistent? After all, only accurate information can be provided for your company's operations using clean data.
Data integrity testing can help with it. It is the method used by the entire industry to assess how easily your data can be retrieved and accessed, allowing you to identify any problems and fix them before they worsen.
This testing is about evaluating accuracy, completeness, and compliance with client requirements throughout the process. Additionally used to ensure that Integrity testing data hasn't been altered or unexpectedly corrupted while accessing the database. Data integrity testing tests are run regularly to check for changes in the database (which is expected to remain unchanged) and to look for new problems brought on by those changes.
Various types of data integrity testing can be performed to ensure the accuracy, consistency, and reliability of data but broadly it can be divided into two ways:
You can make sure that your data stays unchanged even if it is used in different ways and across multiple databases by testing it for logical integrity. This domain has the following four subcategories:
a. Referential Integrity: You must evaluate your database's referential integrity to make sure that data is stored and used consistently. These are the guidelines that define what modifications, omissions, and additions are permitted.
b. Entity Integrity: By testing entity integrity, you can make sure that each entity (person, thing, or combination thereof) in your database has a distinct key and isn't listed more than once.
c. Domain Integrity: By testing domain integrity, you can make sure that the data in a domain is correct and that the formatting, type, and quantity of data entered are all followed.
d. User-Defined Integrity: This describes the constraints that a user places on data to suit their needs. These need to be examined to see if they support data integrity and compliance standards.
This test assesses your data's physical IT architecture and hardware, particularly where it is kept and retrieved. Your database will be protected from natural disasters, human mistakes, storage erosion, accidents, and other dangers by being aware of vulnerabilities and taking steps to reduce them.
When handling this data, developers make certain mistakes, these can be from small to insane levels ones. Below is a review of some common ones:
1. Data frequently depends on other data pieces, systems, or processes. Integrity testing results that are incomplete or erroneous can come from ignoring these dependencies. The interactions and dependencies between various data pieces should be taken into account and tested.
2. Any time data is subjected to a transformation, such as a computation, an aggregate, or a conversion, it is essential to verify the precision and integrity of the resulting data. Failure to verify these conversions could lead to mistakes or discrepancies.
3. Data frequently depends on other data pieces, systems, or processes. Integrity testing results that are incomplete or erroneous can come from ignoring these dependencies. The interactions and dependencies between various data pieces should be taken into account and tested.
4. Any time data is subjected to a transformation, such as a computation, an aggregate, or a conversion, it is essential to verify the precision and integrity of the resulting data. Failure to verify these conversions could lead to mistakes or discrepancies.
5. Testing only a portion of the data or concentrating on a certain area can cause possible problems in other portions of the data to go unnoticed. To make sure that all data is properly checked, thorough test coverage is essential.
6. Lack of realistic data can cause testing to produce misleading results since it does not accurately represent real-world events. For integrity testing to be effective, actual and representative data must be used.
7. The failure to test integrity test data at the limits or boundaries of limitations might lead to vulnerabilities going undetected. To find any potential problems with data integrity, it is crucial to test data that is pushed to its boundaries.
Like data integrity tests, many other testing techniques including localization and automation testing are crucial for any project success. Outsourcing these services can save a lot of time but selecting a reliable partner is even more important. This is where WeTest shines with its automation and localization services with its highly trained staff and stable reputation in the industry. Moreover, WeTest also offers tons of security testing services for mobile apps and game development.
