How Did Time Travel Testing Evolve?

Various software that can conduct time travel testing came about in 1997. Their main purpose was to test a wide range of business logic that could possibly be affected during the turn of the century or the Y2K. During that time, the majority of the software were implemented under a batch mode. In terms of its operation, there were two options. The operator can either run it manually or the software could be operated at a set time.

Twenty years after, different kinds of software have propped up. Some are used by businesses while others are intended for the utilization of regular individuals. The many different kinds of software that we have these days affect us in many ways than before. Let’s take for example the autonomous driving cars, which are basically an automobile being run by a computer, the flying computer or the Boeing 787, and much more. Companies have also turned to technology when it comes to running some of their crucial business operations. Many of these systems run day and night and there are those types that can conduct an internal check to determine if it is payday or if it is a leap year, for instance.

The ubiquity of computers has made time travel testing even more crucial so as to validate the temporal logic of different time sensitive applications these days. Keep in mind that the software used for time travel testing should be precise and it must be conducted in the right environment. Is the point in question for the application related to month-end cycles, quarter end cycles, or perhaps year-end cycles. There are various other date and time sensitive test instances that could be involved in your business operations. A few good examples are checking if the systems have performed correct debt amortization during the appropriate period or perhaps aged uncollected receivables rightly.

For those who run companies, we all know that keeping your ground, staying ahead of your rivals, and dominating your target market needs agility, which is one’s capability to quickly and efficiently adapt to whatever kind of changes that come your way. This trait also means that all the systems you use should be able to adapt to these changes and one good way to mitigate this constant shift is through performing time travel testing. Organizations no longer need to wait until the end of the month, quarter, or year to test their business logic. Through the use of time travel testing, the system would detect a set time and date in order to induce an event or situation that requires validation. This kind of test uses software virtual clocks to achieve this objective. Users can have access to as many as 20,000 virtual clocks. Not only can they be used simultaneously, but they are also very fast and extremely user-friendly.

Virtual time testing is the best alternative to the making changes to the system clock, which calls for the involvement of different administrators and the opening of a ticket. Virtual time testing is also a good option to making alterations to the system clock server, a process that is not only time consuming but may also come with potentially disastrous, though unintended outcomes. There are instances when this bygone method is prohibited in some cases, particularly when the changes to the system clock is being conducted in secure network environments like Active Directory and Kerberos-centered networks. This software allows its users to time travel their system, which needs validation, back into the past or the future through the use of strategically located virtual clocks. This method is not only effective but also helps in reducing the expenses related to testing while increasing the testing team’s productivity.
