Question

### What is Performance Testing?

Answer 1

output:

Performance Testing is a type of testing to determine how a system performs in terms of responsiveness and stability under various workload conditions.

Key aspects include:
1. **Performance Metrics:**
   - Response time
   - Throughput
   - Resource utilization
   - Scalability
   - Reliability

2. **Testing Goals:**
   - Identify bottlenecks
   - Determine system capacity
   - Validate performance requirements
   - Benchmark performance

Answer 2

output:

Common types of performance tests include:

1. **Load Testing:**
   - Tests system behavior under specific load
   - Validates system performance under expected conditions

2. **Stress Testing:**
   - Tests system behavior under peak load
   - Identifies breaking points

3. **Endurance Testing:**
   - Tests system behavior over extended periods
   - Identifies memory leaks and resource issues

Example of JMeter test plan:
<div class="code-block" data-lang="xml"><div class="highlight"><pre><span></span><span class="cp">&lt;?xml version=&quot;1.0&quot; encoding=&quot;UTF-8&quot;?&gt;</span>

<jmeterTestPlan version="1.2">
<hashTree>
<TestPlan>
<elementProp name="TestPlan.user_defined_variables">
<collectionProp name="Arguments.arguments"/>
</elementProp>
<stringProp name="TestPlan.comments"></stringProp>
<boolProp name="TestPlan.functional_mode">false</boolProp>
<boolProp name="TestPlan.serialize_threadgroups">false</boolProp>
</TestPlan>
</hashTree>
</jmeterTestPlan>
