India captain Mahendra Singh Dhoni has urged his team to readjust quickly to Test cricket in order to maintain their spotless home record against Sri Lanka in the format.
India have not played a test since their tour of New Zealand in April and recently suffered a one-day series defeat to top-ranked Australia earlier this month.
Sri Lanka are aiming for their first test series win on Indian soil.
The first test starts at the Motera on Monday.
"We need to shift attention, (having) played a lot of one-day format," Dhoni told a news conference on Sunday.
"After New Zealand, we are playing a test match for the first time, so we have to plan a bit differently."
Sri Lanka, ranked second behind South Africa in the official test rankings, are playing three tests, five one-day internationals and two Twenty20 games on their two-month tour.
"Of course, if you defend every test match, you are defending history," Dhoni said.
"We are not thinking about the history, we are thinking about the test match. If we do well in the test match, it will just add to the history."
India's record-breaking batsman Sachin Tendulkar will complete 20 years in international cricket when he takes the field in the opening test.
Tendulkar, 36, will join a list of 15 players whose international careers have spanned more than two decades.
