# Manual testing of Balkón

## Script 1: Verify generated files

Goals:

  - To verify that Balkón produces the same output in the testing environment
    as it did in development.

  - To verify that ignored files for Git are set correctly.

  - To verify that the files containing expected or "golden" output of tests
    are up to date.

  - To verify that tests are not being skipped.

Prerequisites:

  - Successfully built Balkón from a clone of its Git repository.

Steps:

  1. Clean the Git working tree so that `git status` reports no differences.

  2. Run automated Balkón tests using `cabal run`.

  3. Verify that all tests passed.

  4. Verify that `git status` reports no differences.

  5. Verify that a file named `actual` was generated by automated tests in
     the directory `.golden/shapedRuns/spannedLoremIpsum20em/`.

      - For example by running the command
        `ls -l .golden/shapedRuns/spannedLoremIpsum20em/actual`
        and checking the file's modification time.


## Script 2: Verify visual output

Goals:

  - To identify possible visual problems in the output of Balkón,
    such as incorrectly positioned or scaled glyphs.

Prerequisites:

  - Access to files from the Git repository of Balkón.

  - Successfully built Typograffiti.

Steps:


  1. Run Typograffiti with the font path, face index, pixel size,
     and scale set according to the contents of the file
     `.golden/shapedRuns/spannedLoremIpsum20em/fontInfo` from Balkón,
     and with input set to be read from the file
     `.golden/shapedRuns/spannedLoremIpsum20em/golden` from Balkón.

  2. Verify that text is displayed in the output window.

  3. If necessary, resize the window so that the whole paragraph can be seen.

  4. Verify all of the following:

      a. The displayed text is legible.

      b. The displayed glyphs appear at correct sizes.
         There should be a small amount of blank space around each
         visible glyph so that it does not overlap with its neighbours,
         but not so much that the text feels disconnected.

      c. The displayed text matches `loremIpsumParagraph` from the file
         `test/Data/Text/ParagraphLayout/ParagraphData.hs` from Balkón,
         character for character, except where a space was replaced
         by a line break.

      d. All displayed lines are aligned to the left edge of the output,
         without any indentation.

      e. All displayed lines are broken before words,
         not in the middle of words and not before punctuation marks.

      f. Lines do not appear to be broken too early.

      g. The horizontal space between each pair of adjacent words
         appears equal.

      h. The vertical space between the baselines of two adjacent lines
         appears equal.
