ruby - Test file initialization based off template using ChefSpec -

-

i've got following template file creation in cookbook:

template "my_file"   path "my_path"   source "my_file.erb"   owner "root"   group "root"   mode "0644"   variables(@template_variables)   notifies :restart, resources(service: "my_service") end

and following assertions in chefspec tests:

  chef_run.should create_file "my_file"   chef_run.file("my_file").should be_owned_by('root', 'root')

which results in following failure:

  no file resource named 'my_file' action :create found.

this due fact not using afile resource template resource. question: how can test file creation off template resource using chefspec?

there 2 ways solve problem.

first, can use create_template matcher. match "template" resources in run context:

expect(chef_run).to create_template('my_file')

this matcher chainable, can assert attributes:

expect(chef_run).to create_template('my_file')   .with_path('my_path')   .with_owner('root')

however, matcher won't actually render template. can't check if you've setup file-specificity correctly.

there's top-level matcher kind of "file" (file, cookbook_file, , template) renders contents in memory:

expect(chef_run).to render_file('my_file').with_content(/^match me$/)

you can find more information render_file in readme.

python - TypeError: can only concatenate tuple (not "float") to tuple -

i'm new python, question might easy, anyway, patience: as trying call newton-raphson method calculate implied volatility in black-scholes formula call/put option pricing, first thing is, newton method in scipy.optimize seems calculate function's zeros, in black-scholes formula, want function's value option price, not zero. (i'm new here programming, i'm not sure techniques.) should write function things like: def f(sigma, price): return bsformula(s0,k,r,t,q,sigma) - price then, while calling newton method, takes args=() 1 parameter in function, write this: value = newton(bsprice2, 0.5, args=price) but error message: file "bs.py", line 36, in bsimpvol value = newton(bsprice2, 0.5, args=float(price)) file "/usr/lib/python2.7/dist-packages/scipy/optimize/zeros.py", line 143, in newton q0 = func(*((p0,) + args)) typeerror: can concatenate tuple (not "float") tuple could tell me why that? how fix it? apprecia...
