Dynamic Dates

Legacy Documentation
You're viewing legacy documentation for API Fortress (deployed via an on-premises container). To view documentation for the new SaaS version of API Fortress now known as Sauce Labs API Testing and Monitoring (with Sauce Connect tunnels) see API Testing on the Sauce Labs Cloud.

Have you ever needed to pass a future date as part of the request inside of a test? Perhaps as a check-in or check-out date? You could enter it as static value, but that means you would have to periodically update the date as time went on.

Creating a dynamic date in API Fortress is a simple solution for this sort of situation.

Here's the procedure:

  1. First, open the Composer and add a Set (variable):
  2. In the Variable component editor, enter the following:
    • Var field: enter your variable name.
    • Variable mode field: leave it as _String.
    • Value field: enter the following string: ${D.format(D.plusDays(D.nowMillis(),35), 'yyyy-MM-DD')}.valueField.jpg

Let's analyze the string mentioned above:

${D.format(D.plusDays(D.nowMillis(),35), 'yyyy-MM-DD')}
  • D.nowMillis(): returns the current Unix epoch in milliseconds
  • D.plusDays(): returns the provided milliseconds, plus the provided number of days (in our example, we have added 35 days to today's date)
  • D.format(): creates a timestamp with the given format, using the current timezone (in our example yyyy-MM-DD)

As result, you will have something like 2018-05-15.

You can obtain a past date, starting from today's date with the following string:

${D.format(D.minusDays(D.nowMillis(),35), 'yyyy-MM-DD')}

You can also create a date based on a specified time zone:

${D.format(D.plusDays(D.nowMillis(),35), 'yyyy-MM-DD','America/New_York')}

The above string create the same date as our first example using New York (EST) as the timezone.
