reactjs - Exports defaults else path not taken with Jest and ES6 -

-

i'm having issues pass tests 100% coverage. istanbul exports defaults component else path not taken.

because of that, see in generated html of istanbul tests not @ 100%. in statements , branches tab.

i'm using:

  • react: 15.4.0
  • jest: 17.0.2
  • webpack: 1.12.11

any idea?

enter image description here enter image description here

the problem in jest configuration, using preprocessor in order resolve imports:

in package json had this:

"transform": {   "^.+\\.js$": "<rootdir>/cfg/preprocessor.js" },

this file contained this:

const babeljest = require('babel-jest'); require('babel-register'); const webpackalias = require('jest-webpack-alias');  module.exports = {   process: function (src, filename) {     if (filename.indexof('node_modules') === -1) {       src = babeljest.process(src, filename);       src = webpackalias.process(src, filename);     }     return src;   } };

we updated jest v20 , use module resolver jest, in our package.json added:

"moduledirectories": [   "node_modules",   "src" ],

and removed transform config package.json , preprocessor.js file.

this follow question undefined reference rsa_generate_key in openssl? have openssl program generate rsa key, follows : #include <stdio.h> #include <openssl/rsa.h> #include <openssl/pem.h> int main(int argc, char* argv[]) { rsa *r = null; int ret; r = rsa_new(); bignum *bne = null; ret = rsa_generate_key_ex(r, 2048, bne, null); return 0; } when compile gcc -i../include rsatest.c -lcrypto -l. i undefined reference errors functions in libraries gdi32 , zlib. so correct this, have add -lz , -lgdi32, as gcc -i../include/ rsatest.c -lcrypto -lz -lgdi32 -l. my question is, aren't static libcrypto , libssl self sufficient? in why having add libraries make work? there option should have added while compiling library prevent this? i'm using 64 bit windows mingw compiler. made openssl library of msys , make.
