With the drawback that the qm file need to be generated on each build and the po file needs to be updated on any translations change in the test app BTW: I tried your approach by 1. downloaded po file from https://websvn.kde.org/trunk/l10n-kf5/en/messages/frameworks/kcoreaddons5_qt.po?revision=1522662&view=markup 2. did run lrelease on that file and placed it into kcoreaddons source dir as kcoreaddons5_qt.qm 3. added to top level CMakelists.txt `add_definitions(-DCMAKE_SOURCE_DIR="${CMAKE_SOURCE_DIR}")` 3. add to autotests/kformattest.cpp void KFormatTest::initTestCase() { QLocale::setDefault(QLocale::C); QTranslator *l = new QTranslator(); l->load(QStringLiteral(CMAKE_SOURCE_DIR "/kcoreaddons5_qt.qm")); QCoreApplication::installTranslator(l); } without kcoreaddons-lang package installed the test case returns on a system with installed de_DE strace -e trace=file bin/kformattest 2>&1 | grep \.qm ... access("/home/xxx/src/kf5/kcoreaddons/kcoreaddons5_qt.qm", R_OK) = 0 stat("/home/xxx/src/kf5/kcoreaddons/kcoreaddons5_qt.qm", {st_mode=S_IFREG|0644, st_size=729, ...}) = 0 open("/home/xxx/src/kf5/kcoreaddons/kcoreaddons5_qt.qm", O_RDONLY|O_CLOEXEC) = 5 ~/src/kf5/kcoreaddons-build> bin/kformattest ********* Start testing of KFormatTest ********* Config: Using QtTest library 5.11.1, Qt 5.11.1 (x86_64-little_endian-lp64 shared (dynamic) release build; by GCC 4.8.5) PASS : KFormatTest::initTestCase() PASS : KFormatTest::formatByteSize() PASS : KFormatTest::formatDuration() FAIL! : KFormatTest::formatDecimalDuration() Compared values are not the same Actual (format.formatDecimalDuration(10)) : "10 milliseconds" Expected (QStringLiteral("10 millisecond(s)")): "10 millisecond(s)" Loc: [/home/xxx/src/kf5/kcoreaddons/autotests/kformattest.cpp(302)] FAIL! : KFormatTest::formatSpelloutDuration() Compared values are not the same Actual (format.formatSpelloutDuration(1000)): "1 second" Expected (QStringLiteral("1 second(s)")) : "1 second(s)" Loc: [/home/xxx/src/kf5/kcoreaddons/autotests/kformattest.cpp(318)] PASS : KFormatTest::formatRelativeDate() PASS : KFormatTest::formatValue() PASS : KFormatTest::cleanupTestCase() Totals: 6 passed, 2 failed, 0 skipped, 0 blacklisted, 1ms ********* Finished testing of KFormatTest ********* with installed kcoreaddons-lang ~/src/kf5/kcoreaddons-build> strace -e trace=file bin/kformattest 2>&1 | grep \.qm access("/usr/share/locale/en/LC_MESSAGES/kcoreaddons5_qt.qm", R_OK) = 0 open("/usr/share/locale/en/LC_MESSAGES/kcoreaddons5_qt.qm", O_RDONLY|O_CLOEXEC) = 5 access("/usr/share/locale/de/LC_MESSAGES/kcoreaddons5_qt.qm", R_OK) = 0 open("/usr/share/locale/de/LC_MESSAGES/kcoreaddons5_qt.qm", O_RDONLY|O_CLOEXEC) = 5 access("/home/xxx/src/kf5/kcoreaddons/kcoreaddons5_qt.qm", R_OK) = 0 stat("/home/xxx/src/kf5/kcoreaddons/kcoreaddons5_qt.qm", {st_mode=S_IFREG|0644, st_size=729, ...}) = 0 open("/home/xxx/src/kf5/kcoreaddons/kcoreaddons5_qt.qm", O_RDONLY|O_CLOEXEC) = 5 ```~/src/kf5/kcoreaddons-build> bin/kformattest ********* Start testing of KFormatTest ********* Config: Using QtTest library 5.11.1, Qt 5.11.1 (x86_64-little_endian-lp64 shared (dynamic) release build; by GCC 4.8.5) PASS : KFormatTest::initTestCase() PASS : KFormatTest::formatByteSize() FAIL! : KFormatTest::formatDuration() Compared values are not the same Actual (format.formatDuration(singleSecond, options)): "0 h 00 m 04 s" Expected (QStringLiteral("0h00m04s")) : "0h00m04s" Loc: [/home/xxx/src/kf5/kcoreaddons/autotests/kformattest.cpp(226)] FAIL! : KFormatTest::formatDecimalDuration() Compared values are not the same Actual (format.formatDecimalDuration(10)) : "10 milliseconds" Expected (QStringLiteral("10 millisecond(s)")): "10 millisecond(s)" Loc: [/home/xxx/src/kf5/kcoreaddons/autotests/kformattest.cpp(302)] FAIL! : KFormatTest::formatSpelloutDuration() Compared values are not the same Actual (format.formatSpelloutDuration(1000)): "1 second" Expected (QStringLiteral("1 second(s)")) : "1 second(s)" Loc: [/home/xxx/src/kf5/kcoreaddons/autotests/kformattest.cpp(318)] FAIL! : KFormatTest::formatRelativeDate() Compared values are not the same Actual (format.formatRelativeDate(testDate, QLocale::LongFormat)): "Heute" Expected (QStringLiteral("Today")) : "Today" Loc: [/home/xxx/src/kf5/kcoreaddons/autotests/kformattest.cpp(341)] PASS : KFormatTest::formatValue() PASS : KFormatTest::cleanupTestCase() Totals: 4 passed, 4 failed, 0 skipped, 0 blacklisted, 1ms ********* Finished testing of KFormatTest ********* Seems not to work without further changes What is the drawback to not load any translation in the ECM qm file loader with using QLocale::C as default locale ?
