我想創建Android上使用RxJava一個新的文件,如:RxJava file.createNewFile()總是返回TRUE
public Observable<Boolean> createRx(String name) {
return Observable.just(name)
.map(new Func1<String, Boolean>() {
@Override
public Boolean call(String s) {
File newFile = new File(localPath + "/" + s);
try {
return newFile.createNewFile();
} catch (IOException e) {
throw Exceptions.propagate(e);
}
}
});
}
要正常創建一個新的文件,如:
public boolean createNonRx(String name) {
boolean ret = false;
try {
File newFile = new File(localPath + "/" + name);
ret = newFile.createNewFile();
} catch (IOException e) {
e.printStackTrace();
}
return ret;
}
我JUnitTest代碼和TestReport:
@Test
public void testCreateRx() throws Exception { // FAIL!
TestSubscriber<Boolean> testSubscriber = new TestSubscriber<>();
source.createRx("JunitTest_Create_Rx").subscribe(testSubscriber);
testSubscriber.assertNoErrors();
testSubscriber.assertReceivedOnNext(Arrays.asList(Boolean.TRUE)); //PASS!
source.createRx("JunitTest_Create_Rx").subscribe(testSubscriber);
testSubscriber.assertNoErrors();
testSubscriber.assertReceivedOnNext(Arrays.asList(Boolean.FALSE)); //FAIL!
//expected to be [false] (Boolean) but was: [true] (Boolean)
}
@Test
public void testCreateNonRx() { // PASS!
boolean fstRet = source.createNonRx("JunitTest_LocalDataSource_Create_Non_Rx");
assertTrue(fstRet);
boolean secRet = source.createNonRx("JunitTest_LocalDataSource_Create_Non_Rx");
assertFalse(secRet);
}
我是一個新手,以RxJava,有沒有我的代碼有問題嗎?
爲什麼當我嘗試創建現有文件時,createRx()的調用返回TRUE?
感謝您的任何幫助。
