testing - Is it possible to compile a Go program with specific flags for coverage analysis? -


is possible compile go program specific flags coverage analysis?

the use case:

  • compile app;
  • run functional automated tests;
  • analyse coverage;

should similar gcov or python coverage.

many thanks!

yes, go has cover tool (as of version 1.2) incorporated test process. go test alone compile program , run automated tests may have. adding -cover flag provide statistics on test coverage.

to run it:

go test -cover

you can output coverage profile:

go test -coverprofile=coverage.out

and view with:

go tool cover -func=coverage.out

or

go tool cover -html=coverage.out

for html formatted output (with colour coding).

see http://blog.golang.org/cover , go tool cover -h , go testflag more info.

inversion of control - Autofac named registration constructor injection -

does autofac support specifying registration name in components' constructors? example: ninject's namedattribute . you need use autofac.extras.attributed package on top achieve this so let's have 1 interface , 2 classes: public interface ihello { string sayhello(); } public class englishhello : ihello { public string sayhello() { return "hello"; } } public class frenchhello : ihello { public string sayhello() { return "bonjour"; } } then have consumer class, in want select instance injected: public class helloconsumer { private readonly ihello helloservice; public helloconsumer([withkey("en")] ihello helloservice) { if (helloservice == null) { throw new argumentnullexception("helloservice"); } this.helloservice = helloservice; } public string sayhello() { return this.helloservice.sayhello()...

verilog - Systemverilog dynamic casting issues -

i've code snippet following in testbench function void write_to_port( my_data_type_base data ); my_data_type_extended data_ext; if(!$cast(data_ext, data)); `uvm_error(get_type_name(), "failed cast"); `uvm_info(get_name(), $psprintf("data_ext :\n%s", data_ext.sprint()), uvm_medium) // write data_ext out port.... endfunction when run it, i'm getting uvm_error "failed cast." i'm not quire sure why $cast not returning 1. can see, i'm printing out extended class data item after casting uvm_info. can see it's being cast properly. if don't use $cast if condition, don't runtime error. isn't coding practice use if dynamic cast check if $cast returning 1 ? what might reason behind cast not returning 1 in above case? i think semicolon on line 'if' not belong? i think consumes if statement, , uvm_error executes regardless of how if evaluates: if(!$cast(data_ext, data)); <- no semico...
