Codeceptjs 3.

[cbruyndoncx]

With the release of codecpetjs 3.0 there is a small syntax change
https://codecept.io/wiki/Upgrading-to-CodeceptJS-3.html

( I ) needs to become ( { I } )

I think the only required change is in the testgenerator file

Hello @cbruyndoncx , thank you for the suggestion. This will require upgrading concordialang-codeceptjs-core to version 2.x and derived packages to use codeceptjs@3.

I'm also planning to release Concordia 2 soon. Currently, version 1.x works with codeceptjs 2.x and Concordia 2-alpha.

Yes, I actually started wit a codeceptjs3 installation and installed concordia alongside.
I am just starting with codeceptjs for a project and the combo with concordialang looks promising. Can't wait for v2.0
I was wondering though I found the BNF grammar, but is there an editor you can use that understands the BNF and the other concordialang syntax ?

Since Concordia is inspired by Gherkin, you can use some useful plugins for syntax highlighting.
Although, Concordia has its own reserved words (e.g., Variant, Table) and it would be great to have a fully-compatible plug-in.
The current documentation does not provide a BNF grammar.

An old and incomplete draft goes like this:

feature ::= white comment tags header background? feature_elements comment?
header ::= (!(scenario_outline | scenario | background | variant_background) .)*
feature_elements ::= (scenario | scenario_outline)*
scenario ::= comment tags scenario_keyword space* lines_to_keyword white steps
scenario_outline ::= comment tags scenario_outline_keyword space* lines_to_keyword white steps testcase_sections white
background ::= comment background_keyword space* lines_to_keyword? (eol+ | eof) steps
variant_background ::= comment variant_background_keyword space* lines_to_keyword? (eol+ | eof) steps
tags ::= white (tag (space|eol)+)*
tag ::= '@' ([^@\r\n\t ])+
comment ::= (comment_line white)*
comment_line ::= space* '#' line_to_eol
steps ::= step*
step ::= comment step_keyword keyword_space line_to_eol (eol+ | eof) multiline_arg? white
testcase_sections ::= testcase*
testcase ::= comment space* testcase_keyword space* lines_to_keyword? eol table white
multiline_arg ::=  table | py_string
py_string ::= open_py_string (!close_py_string .)* close_py_string
open_py_string ::= space* '"""' space* eol
close_py_string ::= eol space* '"""' white
cell ::= [^\r\n|]+ '|'
row ::= space* '|' cell+ eol
table ::= row+
step_keyword ::= 'Given' | 'When' | 'Then' | 'And' | 'But'
import_keyword ::= 'Import'
testcase_keyword ::= 'Test Case:'
scenario_outline_keyword ::= 'Scenario Outline:'
scenario_keyword ::= 'Scenario:'
background_keyword ::= 'Background:'
variant_keyword ::= 'Variant:'
variant_background_keyword ::= 'Variant Background:'
property_line ::= '-' space* property connectors content
property ::= [^\r\n|]+
connectors ::= [^\r\n|]+
content ::= value | number
value ::= '"' [^\r\n|]+ '"'
number ::= [0-9]+(\.[0-9]*)?
table_keyword ::= 'Table:'
database_keyword ::= 'Database:'
constants_keyword ::= 'Constants:'
ui_element_keyword ::= 'UI Element:'
ui_element_step_keyword ::= 'Otherwise' | 'And' | 'But'
test_event ::= 'Before All' | 'After All' | 'Before Feature' | 'After Feature' | 'Before Each Scenario' | 'After Each Scenario'
lines_to_keyword ::= (!(eol space* reserved_words_and_symbols) .)*
reserved_words_and_symbols ::= (step_keyword keyword_space) | (variant_background_keyword keyword_space) | scenario_keyword | scenario_outline_keyword | variant_keyword | variant_background_keyword | table_keyword | database_keyword | constants_keyword | ui_element_keyword | test_event | table | tag | comment_line | property_line
line_to_eol ::= (!eol .)*
space ::= ' ' | '\t'
eol ::= '\r'? '\n'
white ::= (space | eol)*
keyword_space ::= ' '

Such BNF would cover the basic syntax. Concordia Compiler uses Natural Language Processing to analyze actions and other constructions.

Hi @cbruyndoncx , while the support for CodeceptJS 3 isn't available, you can upgrade the produced (CodeceptJS 2) tests automatically using codecept3-upgrade, like this:

npx codecept3-upgrade tests

@cbruyndoncx Released in v1.4
