objective c - How can I run Gcov over an installed Cocoa application? -

-

I have a Cocoa app that uses an installer I want to be able to run code coverage on code ( After it has been installed).

This is not a common unit test scenario, where a binary test will run a suit. Rather, the question will interact with the testing UI and the app back-end, while this is going on, so I want to know that GCOV is doing this profiling and then runs a test against it.

Any thoughts?

Update

Why I made this question clear:

The mistake I made was thinking that The object, .gcno and .gcda files were to be installed with binaries (thus making the installer difficult). As soon as the original location of the files is hard-wired in the code, which contains the instrumentation code.

The solution I went with is zipping on the code construction machine and putting it on the test machine on the disk. lcov (or just gcov ) can be run from there. Alternatively, .gcda files will be created on disk and they must be copied back to the machine containing the source code.

Anyhow, the source code should not be present in the install and run time, but if you want to get your results back to the LAKROV-style, then the generated coverage counter file will be mailed to the source code. Should be taken.

The app must compile with the correct GCC flag, which will insert profiling instructions in the code. This is not something you can turn on and off, meaning that your code coverage is modified when compiling time to output information.

Therefore, if you have compiled the app with the correct flag, then this coverage will emit the data, if you have not done it (and you certainly will not want it for such an app. Whom you were going to distribute)

windows - Heroku throws SQLITE3 Read only exception -

After I deploy the app to Heroku, I have to run migration scripts and get this error message ... ITES \ padrino \ prophetmargin & gt; Heroku Rack AR: Rack mutated! SQLite3 :: ReadOnlyException: only one try to write database to read: CREATE TABLE "schema_migrations" ( "version" varchar (255) NOT NULL) /disk1/home/slugs/215264_925fd2c_65a3/mnt/.bundle/gems/gems/ padrino-core- is 0.9.11 / lib / padrino-core / cli / rake.rb: 9: in `init ' how can this be? I also tried to run Heroku dbpush SQLite: //db/my-db.db and that did not work Horoku sqlite3 but using postgres does not do. I'm not sure why you are receiving this error, however, as I have used sqlite3 in development and when pushing it into its travel, they do some magic which migrates to postgrads. I'm absolutely sure how Heroku does 'backwash' this database but it seems that this is happening to you because it's the SQLite db file which is obviously due to Heroku's

lex - Building a lexical Analyzer in Java -

-
I am currently learning lexical analysis in compiler design. To know how a lexical analyzer actually works, I am trying to build myself. I am planning to make it in Java The input to the lexical analyzer is a .tex file that is of the following format. \ section {script} {intro} \ section {Scope} arbitrary text \ section {relevance} uncontrolled text \ subdivision (profit) arbitrary text \ subsubsection {in real life} \ subdivision {Ingredient} \ end {document} The output of the lecture may be a table of contents with a page number in another file. 1 Introduction 1 1.1 Scope 1 1.2 Relevance 2 1.2.1 Benefits 2 1.2.1.1 Real life 2 1.2.2 loss 3 I hope that This problem is within the scope of Language Analysis Read the .exe file and check '\' and continue to check whether it is actually on search In the sectioning command is set to indicate whether or not a flag variable is the type of sectioning. I hope the above approach will work for the construction of Lexa

python - rename keys in a dictionary -

-
I want to change the names of keys in a dictionary which are ints, and I need them so that the inputs with key zero They can sort correctly. For example, my keys are like this: '1', '101', '11' and I may need them: '001', '101', '011' What is doing, but I know that there is a better way tmpDict = {} in the ADC for the old: t MpDict ['% 04d'% int (olden)] = addict [oldkey] New controlled = tmpDict You are going wrong about this if you want to draw entries on a line in a specific way, then you have to sort on the extraction. for sorted (D, key = int): print '% s:% R'% (k, d [k]) < / Div>
