To prevent SQL injection, developers should use ____________ statements or prepared statements.
- Dynamic
- Inline
- Parameterized
- Static
Using parameterized statements or prepared statements helps prevent SQL injection by separating SQL code from user input and escaping special characters.
Scenario: During a test project, you notice that the test execution coverage is low, and defects are being discovered late in the testing process. Which action should be taken based on these metrics?
- Enhance Test Environment
- Improve Test Case Quality
- Increase Test Execution Frequency
- Prioritize Test Case Execution
Improving test case quality is essential in addressing low test execution coverage and late discovery of defects. By enhancing the quality of test cases, testers can ensure better coverage of the system under test and detect defects earlier in the testing process, leading to improved overall software quality.
Why is it essential to perform database testing as part of the software development process?
- To enhance the user interface
- To identify defects in data storage and retrieval
- To increase software scalability
- To speed up the development process
Database testing is crucial because it helps in identifying defects related to data storage and retrieval. By ensuring the accuracy and reliability of data operations, database testing contributes to the overall quality of the software, minimizing the risk of data corruption or loss.
Which of the following is a common encryption algorithm used for securing data in databases?
- AES (Advanced Encryption Standard)
- DES (Data Encryption Standard)
- MD5 (Message Digest Algorithm 5)
- RSA (Rivest-Shamir-Adleman)
AES (Advanced Encryption Standard) is a widely adopted encryption algorithm used for securing data in databases. It offers a high level of security and efficiency, making it suitable for various applications. AES operates using symmetric encryption, where the same key is used for both encryption and decryption, ensuring data confidentiality and integrity.
____________ testing is crucial in CI/CD to ensure that database changes do not introduce regressions.
- Integration
- Performance
- Regression
- Unit
Regression testing in the context of database changes ensures that updates or modifications do not cause unintended side effects or break existing functionality in the system.
In the context of test reporting, what does "defect density" refer to?
- The average time taken to fix a defect
- The number of defects found per unit of code or function points
- The percentage of test cases passed
- The ratio of test cases executed to the total number of test cases
Defect density refers to the number of defects found per unit of code or function points. It helps gauge the quality of the software by identifying how many defects are present in a given amount of code.
Which type of index is designed to improve query performance for columns with low cardinality?
- B-Tree Index
- Bitmap Index
- Clustered Index
- Hash Index
A Bitmap Index is specifically designed for columns with low cardinality, where there are only a few distinct values. It works by creating a bitmap for each distinct value in the column, indicating which rows contain that value. This allows for efficient retrieval of rows matching specific values, making it suitable for columns with low cardinality.
What is the primary purpose of test reporting in software testing?
- To document test cases and test results
- To evaluate the performance of the testing team
- To provide stakeholders with information about the status of testing activities
- To track the progress of coding activities
The primary purpose of test reporting is to inform stakeholders about the current status of testing activities, including progress, issues encountered, and overall quality metrics. This helps stakeholders make informed decisions regarding the software's readiness for release.
Data integrity violations can lead to data ____________, which can have significant consequences for businesses.
- Corruption
- Duplication
- Leakage
- Manipulation
Data corruption due to integrity violations can result in the loss or alteration of data, undermining the trustworthiness and reliability of the information.
What is the role of data encryption in compliance and regulatory testing?
- Ensuring data availability
- Optimizing data performance
- Protecting data integrity
- Safeguarding data confidentiality
Data encryption plays a crucial role in compliance and regulatory testing by safeguarding data confidentiality. Encryption ensures that sensitive information stored in a database remains unreadable to unauthorized users even if they gain access to the database. This helps organizations comply with various regulatory requirements, such as GDPR and HIPAA, which mandate the protection of individuals' personal and sensitive data.
