Time Simulator has put an end to temporal testing. The process of time virtualization enables you split your computer clock into multiple system clocks, while keeping your original computer time intact, and simulating how a program will behave in the future. This new technology, replaces the older process known as temporal testing.
What is Temporal Testing?
Temporal testing is one aspect of dynamic program analysis; the field of expertise where programmers examine how a program will run under a variety of different conditions. One of the most difficult variables to nail down is figuring out how a program will perform days, weeks, and years into the future. If you put valuable time and resources into a program, you don’t want its value to decay over time, making updates more difficult. Therefore, knowing the future behavior of a program is essential.
For the past decade temporal testing had to be done manually by changing the system clock, making the time zone adjustment and running the same program over and over. It was rarely carried out to the full extent needed to make sure that the program would work as well as absolutely possible.
After all, a company only has so much testing workforce. This has led to mistakes with future runs not being spotted in time and program updates causing problems with the original code of the program.
How Does Time Virtualization Differ From Temporal Testing?
In many ways, the ability to conduct time simulations virtually has been a Godsend to programmers. It differs from temporal testing in many respects, mainly that instead of manual testing, it creates the automatic virtual time, or in other words, the program does the work for you.
It splits the system clock into many different clocks, enabling you to run your program under each time simulation. That way, you can spot future errors without manually changing the clock. One such program is Time Simulator, which has the added advantage of allowing you to keep the accurate default clock running on your computer to avoid network security or logging issues when looking back at program files in the future.
The biggest perk of automatic time virtualization is, as mentioned above, the ability to keep your computer running at an accurate time even after running a simulation. This is critical for businesses, particularly in the realm of emails. If your computer is running in the future, and you send an email, many email clients will log the email as spam, and your important email may never be read by the customer, or you may not receive their emails due to computer glitches. Since Time Simulator splits the clock into many parts, you avoid the major flaw which occurs in manual temporal testing.
It is clear that temporal testing works if you need to test one small aspect of a simple program, but for complex applications, temporal testing is simply not convenient or time-efficient enough to run your program. Time virtualization cuts down on program testing times and makes it much easier to examine your program’s future performance.
