Capgemini Performance Test Consultant Interview Questions, Process, and Tips

Throughput is the amount of data transferred per unit time, while hits per sec is the number of requests processed per second.

• Throughput is measured in bytes/sec or bits/sec.

• Hits per sec is measured in requests/sec.

• Throughput and hits per sec are related, but not directly proportional.

• Higher throughput can lead to higher hits per sec, but other factors like server response time and network latency also affect hits per

APIs can be tested in LoadRunner and JMeter using HTTP/HTTPS protocols and by creating virtual users.

• Create a new script in LoadRunner or JMeter

• Add HTTP/HTTPS protocol to the script

• Record the API requests and responses

• Add virtual users to simulate load

• Run the script and analyze the results

Different types of testing include functional, performance, security, usability, and compatibility testing.

• Functional testing ensures that the software meets the specified requirements.

• Performance testing checks the system's ability to handle a large number of users or transactions.

• Security testing identifies vulnerabilities and ensures that the system is secure.

• Usability testing evaluates the user-friendliness of the ...read more

Integrating 3rd party tools with JMeter and LoadRunner

• Identify the 3rd party tool to be integrated

• Download and install the necessary plugin or library for the tool

• Configure the tool in JMeter or LoadRunner

• Use the tool in the performance test script

• Verify the integration by running the test and analyzing the results

Different types of test scenarios in JMeter and LoadRunner

• JMeter: HTTP requests, FTP requests, JDBC requests, SOAP/XML-RPC requests, LDAP requests, etc.

• LoadRunner: Web, Mobile, SAP, Database, Citrix, etc.

• Both tools support load, stress, endurance, and spike testing.

• JMeter supports distributed testing while LoadRunner requires additional licenses for it.

• Both tools allow for parameterization and correlation of test data.

web_reg_save_param API attributes and handling dynamic boundaries

• web_reg_save_param API is used to capture dynamic data from server responses

• Attributes include LB (left boundary), RB (right boundary), ORD (occurrence), and more

• Dynamic boundaries can be handled using regular expressions or custom functions

• Regular expressions can be used to match patterns in the response

• Custom functions can be used to extract data based
