When I am starting my Rspec test, I get this error:
1) User checks if the user is created
Failure/Error: expect{ #user_test = create(:user) }.to change { User.count }

I am really confused about it.
My mongo server is running too.
My user_spec.rb:
require 'spec_helper'
require 'rails_helper'
require 'database_cleaner'
DatabaseCleaner.strategy = :truncation
RSpec.describe User, :type => :model do
it "checks if the user is created" do
expect{ #user_test = create(:user) }.to change { User.count }
end
end
Any idea why my mongo won't work?
Found the answer
My config file had mistake so I change it to :
test:
clients:
default:
database: test
hosts:
- 127.0.0.1:27017
options:
read:
mode: :primary
max_pool_size: 1

I recently added a timeout to a method that is used by about a dozen different commands in the class. Here is the method:
def exec_mc!(command)
begin
Timeout.timeout(30.minutes) do
library_motion_logger ||= ::Logging.logger["#library_logger.name}::Motion"]
library_motion_logger.info("Executing mc command 'mc #{command}' ...")
result = rcm_ssh.execute("/RCM_code/mc #{command}")
# TODO: Can this be the result.success method instead, which checks for empty stderr also
# Match the time pattern from mc
success = result.exit_code.zero?
MotionCommandResult.new(success, result.execution_time, result.stdout, result.stderr)
end
rescue Timeout::Error
# Something is wrong. Fail out now.
library_motion_logger.warn("Timed out while waiting for mc command '#{command}'")
false
end
end
Now when I run rspec, the first spec fails no matter which one is ran first. If I run a single spec, that also fails. Here is what I am seeing as the failure:
1) Library::Motion::MotionCommander#gather behaves like basic motion command with successful result should receive execute("/RCM_code/mc --gather", *(any args)) 1 time
Failure/Error: #library_gem_logger ||= ::Logging.logger[LIBRARY_GEM_LOGGER_ROOT_DEFAULT]
Timeout::Error:
execution expired
As you can see, it says that the error occurs while trying to get the logger in the very first line of my begin block. If I remove this line, I get the same error on the next line. So basically I am always getting an error on the first line of the first spec, no matter what. I have tried moving things around and this has held true. What can I do to fix this?
Edit: Here are some of the specs
def stub_and_expect_mc(exits = [], stderrs = [], stdouts = [])
full_command = "/RCM_code/mc #{command}"
ssh_stub_and_expect(full_command, exits, stderrs, stdouts)
end

end

end

before :each do
stub_and_expect_mc(1)
end
it { is_expected.to have_attributes(success: false) }
end
end

I'm trying to write a simple test for a ruby script that uses gets and I'm experiencing some weird behavior.
When I run the test with rspec it passes fine, but as soon as I run rspec with any flags, like rspec -f json or rspec -O rand the test will fail and give me No such file or directory # rb_sysopen - -O, where -O is whatever the flag that was run.
Stranger still is that if I run rspec and specify the test file like rspec spec/gets_spec.rb, I get a completely different error:
Failure/Error: expect { require_relative '../gets' }.to output("Hello, Lena!\n").to_stdout
expected block to output "Hello, Lena!\n" to stdout, but output "Hello, Describe \"gets.rb\" do!\n"
Diff:
## -1,2 +1,2 ##
-Hello, Lena!
+Hello, Describe "gets.rb" do!
# ./spec/gets_spec.rb:14:in `block (2 levels) in <top (required)>'
I'm having trouble figuring out the right way to write my test so that this doesn't happen but I'm not sure what part of my code needs to change.
I'm using ruby 2.6.3
I learned about testing input from this question
The script, gets.rb, looks like
puts "Hello, #{gets.chomp.capitalize}!"
My test looks like
describe "gets.rb" do
before do
$stdin = StringIO.new("lena")
end
after do
$stdin = STDIN
end
it "should output 'Hello, name!'" , points: 1 do
allow($stdin).to receive(:gets).and_return("lena")
expect { require_relative "../gets" }.to output("Hello, Lena!\n").to_stdout
end
end
Here's the full failure message:
Failures:
1) gets.rb should output 'Hello, name!'
Failure/Error: expect { require_relative '../gets' }.to output("Hello, Lena!\n").to_stdout
Errno::ENOENT:
No such file or directory # rb_sysopen - -O
#./gets.rb:1:in `gets'
# ./gets.rb:1:in `gets'
# ./gets.rb:1:in `<top (required)>'
# ./spec/gets_spec.rb:14:in `require_relative'
# ./spec/gets_spec.rb:14:in `block (3 levels) in <top (required)>'
# ./spec/gets_spec.rb:14:in `block (2 levels) in <top (required)>'
You can try to use a little different approach:
describe "gets.rb" do
it "should output 'Hello, name!'" do
allow_any_instance_of(Object).to receive(:gets).and_return("lena")
expect { require_relative "../gets.rb" }.to output("Hello, Lena!\n").to_stdout
end
end
allow_any_instance_of I took from https://makandracards.com/makandra/41096-stubbing-terminal-user-input-in-rspec
Reading user input in console applications is usually done using Kernel#gets.
The page suggests to use Object.any_instance.stub(gets: 'user input') but it's deprecated syntax already and I've updated it.
I have an issue that's appearing only when running rspec, my application loads and works fine locally and in production

I am working through some Ruby problem sets. I'm using Ubuntu 14.04, rbenv 0.4.0-98-g13a474c, rspec 3.1.4, and ruby 2.0.0p353. I'm running into the following errors for every test I run and I'm hoping someone might be able to guide me in the right direction to a solution.
I have run rspec tests successfully in the past but I can't seem to figure out the issue with my current setup.
Here is the message I receive for every test I run:
6) age is an integer

Edit: Here is an example of one of the spec files, however, the issue comes up on about 20 spec files. I know my solutions are correct and my peers aren't having the same issues I am:

last_name = "R"
age = 23

I was getting the same error (although not following the tutorial).
I believe this setting requires 'rspec/rails'
My solution was to move the line
config.infer_base_class_for_anonymous_controllers = # whatever
From spec_helper.rb to rails_helper.rb.
