CLI: detox test fails to determine a default configuration

[askielboe]

Seems you now have to specify the configuration manually (e.g. detox test -c ios.sim.debug), otherwise detox test crashes.

Description

After upgrading to detox 7.3.X, detox test fails with the following error:

/Users/askielboe/rntest/MyProject/node_modules/detox/local-cli/detox-test.js:37
const platform = (config.configurations[program.configuration].type).split('.')[0];
                                                               ^

TypeError: Cannot read property 'type' of undefined
    at Object.<anonymous> (/Users/askielboe/rntest/MyProject/node_modules/detox/local-cli/detox-test.js:37:64)
    at Module._compile (module.js:649:30)
    at Object.Module._extensions..js (module.js:660:10)
    at Module.load (module.js:561:32)

    at Function.Module.runMain (module.js:690:10)
    at startup (bootstrap_node.js:194:16)
    at bootstrap_node.js:666:3

It seems that program.configuration is undefined (unsurprisingly?). Setting the configuration using detox test -c ios.sim.debug makes detox test work again.

Steps to Reproduce

1. react-native init MyProject
2. Build using Xcode
3. yarn global add detox-cli
4. yarn add detox --dev
5. yarn add mocha --dev
6. Add detox config from Getting Started to package.json, replacing "example" with "MyProject"
7. detox init
8. detox build
9. detox test

Thanks for reporting, this is indeed an issue caused by #639.

A workaround for this (till we publish a fix) would be to explicitly select a configuration:
detox test -c myConfiguration
