Depending on your target projects, JavaScript, TypeScript, or C# may also be useful.

You do not necessarily need to master multiple programming languages. Building a strong foundation in one language is often more useful than learning several languages superficially.

Database and SQL Knowledge

Many applications store important information in databases. Testers may need to verify whether application actions correctly create, update, retrieve, or delete data.

SQL knowledge can help testers perform database validation.

For example:

SELECT * FROM customers;

A tester may use SQL to verify whether information displayed in an application matches the corresponding database records.

Important SQL concepts include:

SELECT
WHERE
ORDER BY
GROUP BY
JOIN
INSERT
UPDATE
DELETE
Aggregate functions
Primary and foreign keys

Database testing knowledge can be particularly useful for enterprise and backend-focused applications.
