What is Database Testing? | Database Testing Checklist and Tools
Database testing has gained a lot of importance in the market. Check out some of the important elements to include in Database Testing Checklist. Most of the organisations prefer having a regular activity. Thus, it has helped a lot of people to take up as a career.
Why Data Mapping in selenium database testing required?
Data Mapping in Database Testing Checklist play a significant role during manual testing activity. It is essential to know about data mapping before starting the testing process.
In software applications, information often melts down from the UI (user interface) to the backend DB and sometimes vice versa. So these are some facets to watch out for to ensure the security of the Database.
Assess whether the fields in the UI/frontend types mapped with all the areas from the DB table. However, the specific mapping advice is available in the requirements records.
Anytime a specific action takes place at the front of the app, then a corresponding CRUD (Create, Retrieve, Update and Delete) activity gets invoked in the backend.
A tester validates the right action. The right action is invoked and that success of invocation is successful or not.
What is ACID Testing in Database Testing Checklist
ACID in DB Testing Checklist is breifly understood or remembered as
- Atomicity
- Consistency
- Isolation
- Durability
Atomicity
When the database queried with a request, the entirety of the query passes back. In short, if you request all kinds of cats in an animal database, you get back a list of all the cats; no dogs or kinds of cats missing from the list.
Issues here mean there is a functionality problem in the database.
If the trailer queries using a petition, this query’s conclusion goes back correctly. In summary, should you ask an assortment of cats within a creature database, then you receive a summary of the cats no puppies or forms of cats right back. Problems here me an actually just really a dilemma is from this database.
Consistency
Each query pulls back consistent results and only valid data stores in the database. Thus, two identical searches should have identical results and no dogs in a database about cats.
Isolation
All queries should remain isolated from each other. Databases have a multitude of queries from different users going at a time. So, these can’t affect each other or the system won’t work.
Durability
It makes sure that stored data is not manipulated by any external factors once a query has occurred. It would be really bad if your server housing the database had a power outage and all the data vanished.
Data Integrity of Database testing in manual testing
For any of the CRUD operations, the updated and most recent values/status of shared data should appear on all the forms and screens. The value should not be updated on one screen and display an older value on another one.
- C: Create – When user ‘Save’ any new transaction, ‘Create’ operation performs.
- R: Retrieve – When user ‘Search’ or ‘View’ any saved transaction, ‘Retrieve’ operation performs.
- U: Update – When user ‘Edit’ or ‘Modify’ an existing record, the ‘Update’ operation of DB performs.
- D: Delete – When a user ‘Remove’ any record from the system, ‘Delete’ operation of DB performs.
Business Rule Conformity in Database Testing Checklist
The tester goes through the design documents through Database Testing Checklist. The tables & joins, dataflow, data types impart more knowledge to the testers. There by more test scenarios and by which better testing of the application.
The bugs which are difficult to find in front-end testing can only found by database testing. Some conditions which you cannot test by front end application tests.
How to test database testing in selenium?
It is important to know about Database Schemes in Database Testing Checklist before knowing to test. A database schema is nothing more than a formal definition of how the data organises inside a DB. To test it:
Identify the requirements based on which the database operates. Sample requirements:
- Create Primary keys before any other fields.
- Foreign keys should be completely indexed for easy retrieval and search.
- Field names starting or ending with certain characters.
- Fields with a constraint that certain values can or cannot be inserted.
Triggers
When a certain event takes place on a certain table, a piece of code (a trigger) can be auto-instructed to be executed.
Stored Procedures
Stored procedures are more or less similar to user-defined functions. These can be invoked by Call Procedure/Execute Procedure statements and the output is usually in the form of result sets.
These sorts in the RDBMS and are available for applications.
Field Constraints
The default value, unique value, and foreign key. Perform a front-end operation which exercises the database object condition
Validate the results with a SQL Query.
Checking the default value for a certain field is quite simple. It is part of business rule validation. You can do it manually or you can use tools like QTP. Manually, you can perform an action that will add value other than the default value of the field from the front end and see if it results in an error.
- The data types of each individual table column should be as per the database design document.
- The table columns should be pointing to the right field in the front end application.
- Test the data retrieval, data insertion, data updating & data deletion either from the front end or using database queries.
- The whole content you will check in Data migration.
Which apps must and should undergo Database Testing?
The database is one of the inevitable parts of a software application.
It does not matter whether it is a web, desktop or mobile, client-server, peer to peer, enterprise or individual business. The database requires everywhere at the backend. Complex and big products that deal with an enormous amount of data.
Similarly, whether it is healthcare, finance, leasing, retail, mailing application or controlling a spaceship. A database is always in action behind the scenes.
As the complexity of applications increases, the need for a stronger and secure database emerges. In the same way, for the applications with a high frequency of transactions (e.g. banking or finance application). The necessity of fully featured DB Tool couples.
Nowadays, we have big data which is large and complex that the traditional databases can’t handle them.
Conclusion
Database testing plays a vital role because it provides extra inputs. It is important to know information and the process of database testing. In other words, it helps in understanding database testing types.
The benefits of the process is many, thus it helps you perform database testing from time to time.
