The Australian Securities Trade (ASX) has automated just over 50 % of the 68,000 check situations desired to assure software underpinning Australia’s fiscal markets remains trustworthy and operating as intended.

A check case is a established of actions carried out on a program to ascertain if it satisfies software specifications and features the right way.

The ASX is seven yrs into check case automation, a journey that started out out with Simon Miller – ASX’s check automation supervisor – and a one duplicate of QuickTest Skilled (QTP).

QTP was originally developed by Mercury Interactive, prior to becoming acquired by HP and then at some point by its latest proprietor, Micro Aim. It is now called unified functional screening (UFT), and remains in use at the ASX.

“It was just me doing the job on one particular platform applying QTP,” Miller advised Micro Focus’ Recognize 2020 ANZ virtual summit. 

“Now obviously I was carrying out the very best occupation I could, but there is only so a lot one particular person can do. There was a lot of lower coverage.”

Quick-ahead seven yrs, and there is now a team of 29 men and women “currently associated in check automation at the ASX, doing the job across all our domains and multiple programs,” he explained. 

There’s also a formal understanding software in location, which was utilised to upskill the current check team, and technical job pathways to offer those men and women progression opportunities.

Upskilling current team was found as crucial mainly because they experienced domain know-how of ASX’s systems.

“Obviously we could have just employed all 29 check automation men and women and been done with it,” Miller explained.

“However, we have a lot of platforms that are distinctive to trade environments and that you’re not likely to come across outdoors [of] there. 

“A lot of our testers have been with the ASX numerous, numerous yrs and experienced a lot of domain know-how, and that is incredibly crucial to us. We needed to make certain we did not eliminate any of that.”

That also speaks to one particular of the aims of introducing extra automated screening – to enhance the dependability of crucial software underpinning Australia’s fiscal markets, minimizing the possibility of bringing new capabilities and features to industry extra quickly.

“We usually set our customers very first, and we assure that our systems and platforms are applying the most current systems to produce the very best focus to our customers,” Miller explained.

“These systems are crucial to the Australian fiscal industry and the Australian financial state in standard. Each thirty day period, we have about 35 million trades just on our equities trading platform on your own, so you can realize some of the numbers that we are likely by way of each individual day. 

“As one particular of our outdated standard managers utilised to like to say, if the industry gets halted, it not only can make the fiscal news but it would basically make headline news as nicely. 

“It does not happen usually, which is an crucial section of what the check team does – ensuring that we are consistent and we have the dependability – but if we shed one particular of these systems [and] experienced to halt the markets, it could possibly value millions to the fiscal financial state.”

Miller explained software engineering and screening procedures in the ASX are now tightly integrated, with check automation embedded into enhancement procedures these kinds of as the exchange’s constant integration and constant enhancement (CI/CD) workflows.

“We have embedded the screening totally into the delivery pipelines and applied modern-day engineering procedures to our screening,” Miller explained.

The enhancement and check groups utilised numerous of the identical equipment and labored to a one established of coding rules that utilize “across the whole of engineering”. 

“All the engineers – that is the builders and the testers – use the identical coding rules to assure consistency. It is all code soon after all,” Miller explained.

To transfer faster, the ASX has also adopted Agile delivery and Scrum methodologies in its software enhancement.

An automation milestone

The trade lately surpassed 50 per cent of its check situations becoming automated.

“We have 56 per cent [automated], and that has truly arrive collectively in the previous pair of months,” Miller explained.

“Everything is coming collectively – we have obtained the training, we have obtained the positions, we have obtained the constant delivery.

“We have 30 yrs of check situations built up, so we have about 68,000 check situations, and we have over 50 % of them automated now, which as you can envision is fantastic for becoming in a position to do our regression screening. I truly feel it is just the starting of what we can do.”

Miller explained that devoid of check automation, programs could acquire months to regression check.

“On some systems the place we have a lot of automation, that … is now calculated in several hours,” he explained.

“As you can envision, it really is greater our velocity to industry. Due to the fact these are repeatable and we operate them each dash, we now have dependability as nicely and we have considerably less defects likely into manufacturing. 

“The systems have to be trustworthy mainly because, as I explained at the start, we have millions of trades likely by way of each one day, and the ASX manufacturer performs mainly because it really is a reliable manufacturer. 

“If we never have the dependability, men and women have the choice to go in other places. They could trade in other markets, which would be using funds specifically out of the Australian financial state.

“So we need to have to make certain that everything performs and have as close to a hundred per cent uptime on all our platforms.”

Miller extra that his team is now starting to demo conduct-driven enhancement (BDD) strategies for automated screening, applying the Cucumber framework and resource.

“BDD is at present on demo on one particular task,” he explained.
