title: How to read testdata/Json in cypress only once system wide?
body: <p>This can be very easy but I cannot find a solution, I have seen pretty much everywhere that to read json from fixture directory one need to use <code>describe</code> which contains test(<code>it</code>) which can use the <code>fixture</code> data.</p>
  <p>Can't there be a way where you just import testdata once, put it in a variable and use that variable pretty much anywhere you want in any of the tests, rather putting the test inside <code>describe</code> which gets the data in fixture.
  I mean its weird you have the read the same json so many times. Especially if its system wide.
  Or
  What would be the solution when you are using <code>cypress-cucumber-preprocessor</code>; you do not have a <code>it</code> block then.
  If conventional way doesn't exist, please provide a clean hack.</p>
