Library to work with phone numbers. It is capable of cleaning and formatting msisdns.

Phones are formatted according to given profile. In mobicont terms profiles are "Профили номерной емкости", they basically describe number's length and prefix (country code).
Profile description format:

length,country_code;length,country_code;...

Country code can be skipped, pair of length and prefix is called msisdn/phone format. Example:

11,7;11;12,380;12,375;12;13

There is special profile Profile.UNLIMITED in the library, that allows msisdns up to 15 signs with any prefixes. This profile correspond to mobicont ValidMSISDNFormat.NO_CHECK_FORMAT_ID constant.

To makeup phone, create PhoneFor instance and call makeup method:

String cleanPhone = new PhoneFor("(909) 695-952-12", new ProfileFor("13,71;13;10,8")).makeup();

cleanPhone will be equal to 7190969595212, as given phone is suitable for 13,71. If given phone does not suit any of the given profile, IlligalArgumentException is thrown.

Please, note,

• that msisdn will be formatted according first suitable format in given profile.
• Russian profile is 11,7, but phone numbers that starts with 8 are also suitable for it. In the example below result will be 89096959512 in both cases

String ruPhone2 = new PhoneFor("8 (909) 695-95-12", Profile.RU).makeup();
String ruPhone1 = new PhoneFor("8 (909) 695-95-12", new ProfileFor("11,7;10,5")).makeup();

• Azerbaijan profile is 12,994, but phones with zero prefix are also formatted as Az:

String azPhone = new PhoneFor("0 854 741 256", new ProfileFor("12,994")).makeup(); // Result is 994854741256

Create new branch, make changes, send a merge request. Someone will review your changes and apply them to the master branch shortly, provided they don't violate quality standards. To avoid frustration, before sending us your merge request please run full Maven build:

$ mvn clean install -Pqulice

• this small library is created according to EO standards, if you do not know what it is, please, visit https://www.elegantobjects.org/

Unit test is junit4 test case started by maven-surefire-plugin. Test method name should be read as an English sentence: TargetClass can methodName as described in "Test Method Names" section in this post: https://www.yegor256.com/2014/04/27/typical-mistakes-in-java-code.html

For assertions "Hamcrest" library is used, so it's good practice to design each test method as single assertion with matching expected result.

@Test
public void returnZero() {
  MatcherAssert.assertThat(
    new TargetClass().action(),
    new IsEqual<>(0)
  );
}

If all test methods are named properly javadocs for them can be skipped with:

@checkstyle JavadocMethodCheck (500 lines)
