Jest - loading text files for string assertions

Question

I am working on a text generator and I would like to compare the generated string with a text stored in a sample files. Files have indentation for some lines and it is very cumbersome to construct these strings in TS/js

Is there a simple way to load text from folder relative to current test or even project root in Jest?

Answer 1

Try this to import your txt into the jest file then compare with it:

const fs = require("fs");
const path = require("path");

const file = path.join(__dirname, "./", "bla.txt");
const fdr = fs.readFileSync(file, "utf8", function(err: any, data: any) {
  return data;
});

expect(string).toBe(fdr)
