unit-testing - 您使用哪些工具/库对您的 PL/PgSQL 进行单元测试

Answer 1

如果我有一个函数public.foo(bar text) returns text...

我创建了另一个这样的函数:

create or replace function test.foo() returns void as $$
begin

  perform assert_equals('stuff', public.foo('thing'));
  perform assert_null(public.foo(null));
  ...

end $$ language plpgsql;

我有一些断言函数，如下所示。我特意使用与 JUnit 相同的名称和签名。

CREATE OR REPLACE FUNCTION assert_equals(expected text, actual text) RETURNS void AS $$
begin
        if expected = actual or (expected is null and actual is null) then
            --do nothing
        else
            raise exception 'Assertion Error. Expected <%> but was <%>', expected, actual;
        end if;

end $$ LANGUAGE plpgsql;

我还有一个运行所有测试的函数:

CREATE OR REPLACE FUNCTION test.run_all() RETURNS void AS $$
declare
    skip constant name[] = '{run_all}';
    test_schema_name constant name = 'test';
    proc pg_catalog.pg_proc%rowtype;
    started timestamptz;
begin

    raise notice 'Time(m)   Name';
    for proc in select p.* from pg_catalog.pg_proc p join pg_catalog.pg_namespace n on pronamespace = n.oid where nspname = test_schema_name and not proname = any(skip) order by proname loop
        started = clock_timestamp();
        execute format('select %s.%s();', test_schema_name, proc.proname);
        raise notice '% %.%()', to_char(clock_timestamp() - started, 'MI:SS:MS'), test_schema_name, proc.proname;
    end loop;  

end $$ LANGUAGE plpgsql;

关于您的问题:

What percentage of your code is covered by unit tests and how do you measure it?

不确定。我想我需要一个代码覆盖工具。

更新:看起来您可以使用 https://github.com/kputnam/piggly 检查代码覆盖率

How do you decide which modules to unit test first?

最complex那些。

Do you think the time and effort which you invested in your unit testing harness has paid off or not?

非常高兴我正在使用单元测试。
