Android更改测试的语言环境
我想测试当用户更改语言时字符串是否正确更新。我正在使用Android更改测试的语言环境,android,kotlin,Android,Kotlin,我想测试当用户更改语言时字符串是否正确更新。我正在使用Espresso测试字符串是否与正确的语言环境匹配,目前我正在这样更改它: private fun changeLocale(language: String, country: String) { val locale = Locale(language, country) Locale.setDefault(locale) val configuration = Configuration() config
Espresso
测试字符串是否与正确的语言环境匹配,目前我正在这样更改它:
private fun changeLocale(language: String, country: String) {
val locale = Locale(language, country)
Locale.setDefault(locale)
val configuration = Configuration()
configuration.locale = locale
context.activity.baseContext.createConfigurationContext(configuration)
getInstrumentation().runOnMainSync {
context.activity.recreate()
}
}
问题是,在View(withText(预期)).check(matches(isDisplayed())上的浓缩咖啡测试断言为false,因此我想知道在运行测试之前设置默认区域设置的正确方法是什么?根据答案,您可以通过编程方式更改区域设置:
public class ResourcesTestCase extends AndroidTestCase {
private void setLocale(String language, String country) {
Locale locale = new Locale(language, country);
// here we update locale for date formatters
Locale.setDefault(locale);
// here we update locale for app resources
Resources res = getContext().getResources();
Configuration config = res.getConfiguration();
config.locale = locale;
res.updateConfiguration(config, res.getDisplayMetrics());
}
public void testEnglishLocale() {
setLocale("en", "EN");
String cancelString = getContext().getString(R.string.cancel);
assertEquals("Cancel", cancelString);
}
public void testGermanLocale() {
setLocale("de", "DE");
String cancelString = getContext().getString(R.string.cancel);
assertEquals("Abbrechen", cancelString);
}
public void testSpanishLocale() {
setLocale("es", "ES");
String cancelString = getContext().getString(R.string.cancel);
assertEquals("Cancelar", cancelString);
}
}
您可以轻松地将代码转换为Kotlin。根据我的经验,在运行时设置语言环境是不可靠的。关于这个话题,这家伙还有很多话要说:
您应该尝试使用Firebase Test Lab或类似服务,并在不同的设备(设置了不同的区域设置)上运行测试。Kotlin版本,基于@Adib Faramazi的帖子
private fun setLocale(language: String, country: String) {
val locale = Locale(language, country)
// here we update locale for date formatters
Locale.setDefault(locale)
// here we update locale for app resources
val context: Context = getApplicationContext()
val res: Resources = context.resources
val config: Configuration = res.configuration
config.setLocales(LocaleList(locale))
res.updateConfiguration(config, res.displayMetrics)
}
