unit testing - mocking creation of an array with powermock java -

-

i write test following function in java.i want mocking creation of array.

public file[] myfunc() {     file[] array = new file[2];   return array;  }

i have wrote following test using powermock java:

@test  public void test1() {   file f1 = createmock(file.class);   file[] files = new file[]{f1};   expectnew(file[].class).andreturn(farray);   replayall();   file[] res = myclass.myfunc();   verifyall();  assertequals(f1, res[0]);  }

it throws exception following message: org.powermock.reflect.exceptions.constructornotfoundexception: no constructor found in class java.io.file parameter types:<none>

the exception says it: attempt create file instance without specifying constructor arguments there no constructor without parameters class java.io.file. stack trace of exception tell code location of attempt. guess, file f1 = createmock(file.class);. check powermock documentation alternatives.

-
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...
