Rake db: test: prepararsi nell'app Rails 3 non riesce con il file non trovato

Question

Non sono sicuro del motivo per cui tutto questo accade all'improvviso. Mi piacerebbe sapere come risolvere, per favore, se qualcun altro si è imbattuto in questo prima o ha idee su dove cercare. L'uso di bundle exec non risolve, ha lo stesso comportamento.

versione rastrello 0.9.2.2 rotaie versione 3.2.1 versione rspec 2.8.0

Answer 1

Questo è ciò che accade quando qualcosa (un gioiello, per esempio), ha una linea che fa qualcosa di semplice come questo:

require 'test/unit' 

Questo file has an at_exit hook che tenta automaticamente di eseguire i test, utilizzando l'ultima "frase" nel comando come il nome del test da eseguire. Questo è il motivo per cui non è possibile trovare db:test:prepare.

Ad esempio, la gemma shoulda-context fa questo. Lo stavamo usando in Spree e abbiamo avuto lo stesso problema di te. Ho aperto uno pull request to fix this issue.

Answer 2

Forse un percorso non utile, ma hanno hai cambiato qualcosa nel tuo ambiente di sviluppo di recente? Ti piace cambiare XCode? Stavo succedendo un sacco di cose strane fino a quando non sono stato ricostruito con l'osx-gcc-installer.

Onestamente, questo sembra qualcosa al di fuori di una gemma spezzata, ma non ho potuto nemmeno spiegare molti dei miei errori.

Answer 3

posso riprodurre un errore molto simile in diverse circostanze (rotaie esterne):

• MRI 1.9.3-p125
• Rake 0.9.2
• Rakefile: Rake::TestTask.new
• test/test_foo .RB: require "test/unit"

(lamenta test/test * .RB non trovato, stesso stack)

Soluzioni alternative:

• aggiornamento a rastrellare 0.9.2.2
• Downgrade alla RM 1.9.3-p0
• aggiornamento a test/unit 2.x https://github.com/test-unit/test-unit

Dato questo, forse dare una seconda occhiata al rake. In particolare se si utilizza bundler, provare bundler exec rake ... anziché solo rake ...?

Answer 4

sono stato in grado di risolvere questo problema con l'aggiunta di una "gemma 'test-unit'" linea al mio Gemfile

Answer 5

Questo ha funzionato per me:

Gemfile:

gem 'shoulda-context', require: false 

test_helper.rb :

require 'shoulda-context'
