Conditionally run tests in Jest
const itif = (condition) => condition ? it : it.skip; describe(‘suite name’, () => { itif(true)(‘test name’, async () => { // Your test }); });
How do threads and number of iterations impact test and what is JMeter’s max. thread limit
The max number of threads is determined by a lot of factors, see this answer https://stackoverflow.com/a/11922239/460802 There is a big difference in what you are proposing. “500 threads, Loop 1 ” Means 500 threads AT THE SAME TIME doing the loop ONCE. “50 threads, loop 10” Means only 50 threads AT THE SAME TIME doing … Read more
What is [Cycle Detected] with memory leak?
What Is [Cycle Detected] when viewing managed memory? When viewing Heap snapshots inside Visual Studios Diagnostic tools you have: The Object Type Window which shows objects held in memory. When you select a particular Object Type, you can access: Paths to Root – Don’t be fooled by the fact this information is presented in a … Read more
How to load 100 million records into MongoDB with Scala for performance testing?
Some tips : Do not index your collection before inserting, as inserts modify the index which is an overhead. Insert everything, then create index . instead of “save” , use mongoDB “batchinsert” which can insert many records in 1 operation. So have around 5000 documents inserted per batch. You will see remarkable performance gain . … Read more
I need a slow C# function
Try to calculate nth prime number to simulate CPU intensive work – public void Slow() { long nthPrime = FindPrimeNumber(1000); //set higher value for more time } public long FindPrimeNumber(int n) { int count=0; long a = 2; while(count<n) { long b = 2; int prime = 1;// to check if found a prime while(b … Read more
Measure full page size in Chrome DevTools
In the Network tab, make sure ‘Disable cache’ is checked and then when you load a page, look at the bottom panel for the total transfer size. See screenshot below: The individual sizes are rounded, but the total at the bottom uses the byte size, which you can see in the HAR. The total then … Read more
Prometheus – Convert cpu_user_seconds to CPU Usage %?
Rate returns a per second value, so multiplying by 100 will give a percentage: rate(container_cpu_user_seconds_total[30s]) * 100
Is JUnit the right tool to write performance tests? [closed]
There may be better approaches, but there are also some frameworks that help implement benchmarking with JUnit. Some useful practices are warmup runs, statistical evaluations. Take a look at JUnitBenchmarks and JUnitPerf EDIT looks like JUnitBenchmarks has been deprecated since the question has been stated. The project’s maintainers recommend moving on to JMH. Thank you, … Read more
Java Performance Testing [duplicate]
The one flaw in that approach is that the “real” time doSomething() takes to execute can vary wildly depending on what other programs are running on the system and what its load is. This makes the performance measurement somewhat imprecise. One more accurate way of tracking the time it takes to execute code, assuming the … Read more
