testdate

Keeping dates in test date fresh and relevant.

Description

Whenever you have are developing an application that involves dynamic behaviour based on time you run into issues with stale test dates. You need to have dates in your test data, but wever now and then tests may fail due to dates going over some threshold. Those days are gone!
With testdate you can make all your dates in testing relative to now. No limitations of file types, as long as it's plain text.

Installation

npm install @endran/testdate --save

or

yarn add @endran/testdate

Usage

Before you seed your database solution with test data run:

testdate \
    --source myTestData.augmented.csv \
    --destination myTestData.csv \
    --format "YYYY-MM-DD HH:mm:ss"

This will scan the --source file for keywords, and output fresh data to --destination. See https://devhints.io/moment for all --format options. Use --override an existing destination file, by default it will not override anything. If you want you can use punctuation marks around your data, for example when working with JSON it's nice to wrap testdate in "...", use --marks to denote the amount of marks that need to be removed.

Keywords

The --source file will be scanned for keywords. You modify dates relative to now, and you can also fix time of day. It's also possible to override formatting for a specific date.

With fixed time and custom format : __TESTDATE_now-0000-01-00@19:00:00#dddd, MMMM Do YYYY_TESTDATE__...

Everything between __TESTDATE_ and _TESTDATE__ will be considered, folowing these requirements:

• Starts with either now+ or now-, to indicate to add or substract time relative to now.
• Required after now, continues with date:
  • First years, YYYY (required).
  • Then months, MM.
  • Then days, DD.
• Optionally for time, either; T for time relative to now; Or @ for fixed time of day.
  • Hours, HH.
  • Minutes, mm.
  • Seconds, ss.
• Optionally, to add custom format for a single line, append with #<yourFormat>.
• Optionally, to add punctuation marks for a single line, append with %<numberOfMarks>.
  • Even if you do not need custom formatting you do need to add the # token, use like #%<numberOfMarks>.
• Each date instance must be on a single line, it may not span 2 lines.
