Gregor,
when I am doing an osc build locally all packages that are specified in the "BuildRequires" tags are installed in a isolated environment.
Quite.
Is the same possible for packages (including their versions) needed at runtime, i.e. specified by the "Requires" tags?
Needed? Or wanted? If your software will not work at runtime without a specific version of the library or other package on which your software depends, then yes, it is not only possible, but advisable.
The software needs a _minimum_ version of a dependent package but this fact was not automatically detected by rpm, see below.
My goal is to run some unit tests of packaged software to ensure the Requires dependencies are specified correctly without having to test it on a separate test machine.
Perhaps I do not understand your question quite correctly, but, here's my summary:
Guaranteeing correct package versions at runtime is exactly what the 'Requires' tag accomplishes for you.
Probably I am not familiar with the correct technical terms. I try to describe my scenario in more detail: 1) I created a package for a QT application [1] without secifying any Requires tag. 2) I installed the package on my machine. No problem when executing the app because (among others) libQt5Core 5.3 was already installed. 3a) I installed the package on another openSUSE 13.1 machine via YaST-1-Click-Install. 3b) To resolve dependencies libQT5Core 5.1 got installed automatically from openSUSE 13.1 repos. 3c) When execute the app I got a runtime failure because libQT5Core >= 5.2 is required. 4) To fix it, I specified Requires: libqt5-qtbase >= 5.2 So my question is if it is possible to have a sandboxed environment on my dev machine where I can test _in advance_ if the Requires tag is needed on non-dev maschines. - Gregor
Are you asking about the syntax of the Requires tag? Here are some examples for a piece of software which would (respectively) require any version of frobnitz, or any version newer than 1.2.0 or a dependency requiring exactly frobnitz-1.1.7 [0]. There is no question about the syntax. Thanks.
