Busted can't run multiple tests: Error → Nil error

[andrew141]

Hello everybody, I have a problem with running multiple tests via busted. I have 3 simple test scripts:

• test_script_1_spec:

  describe("Test script 1", function()
  setup(function()
      print("\nSetup function for Test script 1")
  end)
  it("Test function for Test script 1", function()
      print("Test function for Test script 1")
  end)
  end)

• test_script_2_spec:

  describe("Main test script 2 (with terra require)", function()
  setup(function()
      print("\nSetup function for Main test script 2")
      require "terra"
  end)
  it("Test function for Main test script 2", function()
      print("Test function for Main test script 2")
  end)
  end)

• test_script_3_spec:

  describe("Test script 3", function()
  setup(function()
      print("\nSetup function for Test script 3")
  end)
  it("Test function for Test script 3", function()
      print("Test function for Test script 3")
  end)
  end)

The problem is when I run them with command busted or busted -c, because after second test script there's an error saying:

Error → Nil error
suite spec/test_script_3_spec.lua

• I tried to run them manually one by one - all tests have passed
• I tried to run them together with command busted ./spec/test_script_1_spec.lua ./spec/test_script_2_spec.lua ./spec/test_script_3_spec.lua - the same error appeared
• I tried to put the second test script as the last one to execute (busted ./spec/test_script_1_spec.lua ./spec/test_script_3_spec.lua ./spec/test_script_2_spec.lua) - all tests have passed
• I tried to delete the line requiring terra from the second script - all tests have passed

It seems like requiring terra causes an error due to which the following test scripts cannot be executed. My version of Lua is LuaJIT 2.1.0-beta3 -- Copyright (C) 2005-2017 Mike Pall. http://luajit.org/ And I have terra installed with Luapower (distribution for LuaJIT, Terra and OpenResty). Does somebody know how to deal with this type of error, please? I would appreciate any help. Thank you very much and have a nice day.

Use the verbose flag on the command line

[andrew141]

@Tieske thank you for your hint, so I tried busted -v (as well as busted --verbose) and here's the output:

root@2626552b0fa8:/luadev/luaserver# busted -v

Setup function for Test script 1
Test function for Test script 1

hmmm... some output options do not display set up error properly, try for example -o TAP and see if that adds more info

[andrew141]

@Tieske thank you, seems like that helped a little, there's longer output with -o TAP:

root@2626552b0fa8:/luadev/luaserver# busted -o TAP

But anyway, I'm still struggling with the error, I don't know what's wrong with terra.

Did you ever figure this out @andrew141?

[andrew141]

@alerque Hi, probably yes (as I passed the subject in school), but now I'm not sure what really helped my scripts. I was solving this problem more than one year ago and I don't remember the solution, I'm sorry.

[alerque]

Fair enough. If anybody ever bumps into the same thing and ends up here with a Google search or whatever feel free to drop a comment and we can look into it further.
