Performance Tester Diary - Episode 2

This is Chapter 2 of our journey of non-functional testing with Otto Perf. You can read Chapter 1 if you have missed it.

Authors note

The article is in the OctoPerf Blog pages

Otto had previously got to the point where he had defined a set of non-functional requirements and risk assessed these with the programme team. Otto had also had the opportunity to be involved in the design process which had allowed him to encourage the architects, and development leads to consider application performance as part of their architectural design principles. In this chapter we will follow Otto’s progress as he starts to consider how he is going to write his performance tests and how he will incrementally write tests in line with the development activity. Otto will also consider how he can make sense of the performance tests results he will gather and how he will ensure that the infrastructure is fit for purpose.

Performance Tester Diary - Episode 1

This is the first in a series of posts that are going to follow the fictional performance tester Otto Perf. Otto manages all aspects of performance testing for a fictional company OctoCar that specialise in selling used cars.

OctoCar are building a new system to manage the selling of their fleet of cars, and we are going to follow Otto on his journey as he ensures that the new technology platform performs in line with agreed non-functional requirements under peak volumes of load and concurrency.

We wanted to document the journey of performance testing through the delivery lifecycle of a new application from start to finish and look at how the non-functional testing process could be followed as the application is delivered.

Our blog posts normally focus on a singular aspect of the non-functional testing lifecycle and do not always consider the wider picture of non-functional testing, something that this series of posts will do.

Feature Highlight - Import JTL results from JMeter

OctoPerf offers a JTL import feature that allows anyone to import JMeter results and manipulate them through our reporting UI for free.

What is JTL

JTL stands for Jmeter Test Logs. It is the recommended output for JMeter test results.

It is basically a CSV file that contains a single line for each individual sample result:

jtl-file

It is important to note that the JTL is not structured, it contains results for a given JMeter instance across all threads running. Because of this it can be difficult to differentiate items that share a similar label.
