By knowing the underlying concepts of how the software works, the tester makes better-informed testing choices while testing the software from outside. Typically, a grey-box tester will be permitted to set up an isolated testing environment with activities such as seeding a database. The tester can observe the state of the product being tested after performing certain actions such as executing SQL statements against the database and then executing queries to ensure that the expected changes have been reflected. Grey-box testing implements intelligent test scenarios, based on limited information. This will particularly apply to data type handling, exception handling, and so on.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What does the tester execute while preforming certain queries?
Ah, so.. unanswerable

In the 7th century, the Frankish merchant Samo, who supported the Slavs fighting their Avar rulers, became the ruler of the first known Slav state in Central Europe, which, however, most probably did not outlive its founder and ruler. This provided the foundation for subsequent Slavic states to arise on the former territory of this realm with Carantania being the oldest of them. Very old also are the Principality of Nitra and the Moravian principality (see under Great Moravia). In this period, there existed central Slavic groups and states such as the Balaton Principality, but the subsequent expansion of the Magyars, as well as the Germanisation of Austria, separated the northern and southern Slavs. The First Bulgarian Empire was founded in 681, the Slavic language Old Bulgarian became the main and official of the empire in 864. Bulgaria was instrumental in the spread of Slavic literacy and Christianity to the rest of the Slavic world.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): When was Carantania founded?
Ah, so.. unanswerable

Japan used the name Greater East Asia War (, Dai To-A Senso?), as chosen by a cabinet decision on 10 December 1941, to refer to both the war with the Western Allies and the ongoing war in China. This name was released to the public on 12 December, with an explanation that it involved Asian nations achieving their independence from the Western powers through armed forces of the Greater East Asia Co-Prosperity Sphere. Japanese officials integrated what they called the JapanChina Incident (, Nisshi Jihen?) into the Greater East Asia War.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What did Japan call the occupied group of Asian nations?
Ah, so..
Greater East Asia Co-Prosperity Sphere
