c# - How to upload a file to an endpoint from an integration test -


when file uploaded client, can found in this.request.files, of type httpfilecollectionbase.

httpfilecollectionbase contains httppostedfilebase entries.

the properties on these objects read-only, hoping setup mocks. mock request return mock httpfilecollection, , collection contain 1 mockhttppostedfile. inputstream property on object return filestream object instantiate using real file in source control.

  1. is approach uploading file endpoint integration test?
  2. if approach, how can mock out moq?
  3. if not approach, can suggest better way?

thanks!

i know nothing asp.net mvc, looks need setup mock dependencies:

memorystream stream = new memorystream();  var mockfile = new mock<httppostedfilebase>(); var mockfiles = new mock<httpfilecollectionbase>(); var mockrequest = new mock<httprequestbase>();  mockfile.setup(f => f.inputstream).returns(stream);  // if example, index file name. mockfiles.setup(f => f[it.isany<string>()]).returns(mockfile.object);  mockrequest.setup(r => r.files).returns(() => mockfiles.object);  // write expected data memory stream, instantiate class  // under test using mockrequest.object

in unit test, use memory stream rather file, file stream works same.

if want avoid having mock out , set these dependencies, put them behind uploadedfiles abstraction, make code depend on abstraction, , mock uploadedfiles. need thin wrapper around request.files file stream name (or access them). better because downstream code depends on uploadedfiles, stream , string, rather httprequestbase, httpfilecollectionbase, httppostedfilebase, stream , string.

setup simplified this:

memorystream stream = new memorystream(); var mockuploadedfiles = new mock<uploadedfiles>(); mockuploadedfiles.setup(u => u.getfile(it.isany<string>())).returns(stream);

c++ - Is it possible to compile a VST on linux? -

for class project i'm attempting write vst plugin backed cuda. current cuda workflow on linux box, i'd prefer compile , link there. according wikipedia , should possible (i couldn't find steinberg documentation relevant linux) can't find makefile or instructions on how build if aren't using xcode or visual studio. i'm vst 3 sdk doesn't support linux. when try compile plugin under linux, error: ./base/source/fatomic.cpp:39:30: fatal error: libkern/osatomic.h: no such file or directory this issue caused following code in "vst3 sdk/base/source/fatomic.cpp" #if mac #include <libkern/osatomic.h> #if mac_os_x_version_min_required > mac_os_x_version_10_4 #define native_atomic_type (volatile int32_t*) #else #define native_atomic_type (int32_t*) #endif #elif windows #include <windows.h> #endif but hope compiling under linux work vst sdk 2.4. reading. jvstwrapper seems run on lin...

while using php cli in ubuntu got apache web server cant read file can while using in browser. , error shows nothing , next used code testing purposes : <? $handle = fopen("testfile.txt", "r"); if ($handle) { while (($buffer = fgets($handle, 4096)) !== false) { echo $buffer; } if (!feof($handle)) { echo "error: unexpected fgets() fail\n"; } if(!is_readable($handle) { die("not readable"); } fclose($handle); } ?> how fix ? edit : after removing '@' before fopen got following error fopen(testfile.txt): failed open stream: no such file or directory in /var/www/log/ka.php on line 2 when run script through cli, uses shell's working directory, in opposition file's directory (which apache hands current directory). important you, since fopen call depends on relative path; , relative paths resolved relatively working directory, not script. to have script behave apache, eit...
